LIVRO de dois professores e investigadores sobre a AVALIAÇÃO IMOBILIÁRIA entra em circulação no mercado no fim de Julho de 2021.
O livro resulta do trabalho de várias décadas de experiência e de investigação dos autores que são também professores em diversos cursos de pós-graduação em análise de investimento e avaliação imobiliária.
A Avaliação Imobiliária é uma área do conhecimento transversal que está associada aos ramos do conhecimento da Engenharia Civil, Urbanismo, Economia e também do Direito.
Segundo os AA. a Avaliação Imobiliária é, amiúde, tratada de forma muito ligeira em Portugal, o que tem levado a que indivíduos, com pouco conhecimento sobre o tema, acreditem saber mais do que outros mais bem preparados, fazendo com que tomem decisões erradas e cheguem a resultados indevidos.
Trata-se de uma Obra com 650 páginas, ilustrada a cores e com inúmeros exemplos numéricos, que vem permitir, aos profissionais envolvidos na Avaliação de Imóveis, criar as necessárias bases sólidas para justificar, nas suas análises e tomadas de decisão, os valores de avaliação nos mais diferentes âmbitos e tipos de abordagens.
O Livro, acreditam os autores, irá contribuir para que “os avaliadores iniciados se inteirem das bases científicas e técnicas fundamentais da avaliação imobiliária, e que os avaliadores experimentados as apliquem de forma enquadrada e devidamente sistematizada, por forma a que ambos abordem com eficácia e eficiência os diversos problemas da Avaliação Imobiliária”

The new chapters cover structural loads, fracture mechanics of concrete and composites, railroad bridges, health monitoring of structures, building information modeling (BIM), structural fire engineering, progressive collapse and blast-resistant design, strengthening of concrete using fiber-reinforced polymer (FRP), structural glass, design of foundations for machines, value engineering, and stone cladding.
The 33 chapters of the handbook have been written by 66 contributors. They have presented their material in a ready-to-use form with flowcharts to show step-by-step procedures wherever possible. Therefore, derivations of formulas are omitted in all but a few instances, and many worked-out examples are given. Background information, descriptive matter, and explanatory material have been condensed or omitted. Because each chapter treats a subject that is broad enough to fill a book by itself, the contributors have had to select the material that, in their judgment, is likely to be the most useful to the greatest number of users. References and sources of additional material are noted for most of the topics that could not be treated in sufficient detail.
The constant search to maximize the transparency of the façades resulted in larger glass windows forcing concrete and steel load-bearing systems to become smaller over time.
.......................................................................................................
External cladding of buildings was regarded, along the last decades, as an aesthetic “well-regarded” solution with no need for relevant maintenance works and costs.
Natural stone-clad façades make a significant contribution to the overall aesthetic and technical performance of a building. They have a substantial effect on people’s judgment about visual impact, yet they submitted to a variety of actions such as heat, air, and moisture actions or dynamic loadings such as wind and seismic effects.
Durability, environmental compatibility, and economic sustainability along with mechanical, chemical, thermal, hygrometric, and other weathering “actions” are the key aspects that must be addressed together with the strength and structural safety.
Several methods or systems are available for installing stone on the exterior of buildings depending on the manner how the environment and exposure conditions are addressed. Temperature changes, air pressure, water, in any form, as direct or indirect induced tensions must be undertaken appropriately, based on a robust empirical investigation encompassed with lessons from older thin-stone cladding building’s façade systems.
Under the structural point of view, numerous techniques were employed to support the stone panels, both within curtain walls as well as individually. The development of curtain wall systems, consisting of vertical and horizontal structural members, connected and anchored to the supporting structure and the notable stones’ cutting technology provides all the normal functions of a curtain wall, using thin cladding slabs or panel as its skin. Figure 33.1 is an example of a curtain wall system providing a ventilated façade.
Façade veneer systems must comply with structural safety requirements in particular for direct actions such as the inertial forces on heavy stone cladding panels that are more susceptible to earthquake damage. In some regions, wind action acting in lighter panels may be more stringent than seismic action. Stone cladding failure can induce serious injury to people and may cause relevant financial losses.

When subjected to tensile stress, glass break with any plastic flow because it is a brittle material. The break occurs at a stress level much lower than the theoretical value calculated from the strength of the atomic bonds. The glass is unique since its fracture occurs in entirely different ways from other materials. Glass failure generally starts at a specific surface flaw which is as a stress multiplier in a region of high tensile stress.
Failure prediction methods based on allowable areas for each thickness of glass as a function of uniform duration pressure have been replaced by modern methods that have the advantage of providing a consistent framework for all previous testing as also explains most of the phenomena associated with laterally loaded thin glass plates ...

É ainda merecedora de destaque, pelo seu significado e relevância, a preocupação didáctica manifestada pelo autor, ao incluir exemplos práticos de aplicação dos diferentes temas tratados ao longo do livro, o que constitui uma significativa mais valia da obra em apreço, desde logo para os estudantes dos cursos de engenharia, mas também, seguramente, para os profissionais envolvidos no projecto de fachadas envidraçadas.
A temática abordada – comportamento estrutural de fachadas envidraçadas - a que acresce o rigor científico e técnico com que é tratada, tornam este livro, caso único em língua portuguesa, uma obra de consulta obrigatória para todos quantos se dedicam ao projecto e construção deste importante elemento construtivo.
Inscrevendo-se, claramente, pela sua natureza, no campo da engenharia, o presente livro não deixa de constituir, por esse motivo, uma obra igualmente útil para estudantes e profissionais de arquitectura, que aqui encontrarão ampla e detalhada informação que em muito os auxiliará na concepção e desenho de fachadas envidraçadas.

Straightforward formulae are provided for computing action on cladding, with special emphasis on the effect of seismic forces, including an extensive general methodology applied to non-structural elements. Based on the Load and Resistance Factor Design Format (LRDF), minimum slab thickness formulae are presented that take into consideration stress concentrations analysis based on the Finite Element Method (FEM) for the most commonly used modern anchorage systems. Calculation examples allow designers to solve several anchorage engineering problems in a detailed and objective manner, underlining the key parameters. The design of the anchorage metal parts, either in stainless steel or aluminum, is also presented.

dimension stone cladding of rainscreen fac¸ades. Based on a number of mechanical tests using various types of
Portuguese stone – three igneous, two sedimentary and one metamorphic – a study was carried out to investigate the
relationship between the flexural strength and breaking load of specific and very common stone types. Several
physical and mechanical characterisation tests and 130 pull-out tests with 6 and 8 mm cone bolt threads were
performed to determine the pull-out load failure on six different stone types: three granite, two limestone and one
marble. Finite-element stress analyses were carried out, and the test results were the basis for calibrating a simple
formula that can be used to estimate the stone’s breaking load at the undercut anchorage. Stress concentration
factors are proposed to take into account the undercut drill hole geometry and the specific properties of each type of
stone. Stone specimens from the same batches were subject to pull-out force tests using dowel anchorages, whose
values were then compared with the breaking load of undercut anchorages. Results are discussed and conclusions are
drawn based on tensile stress values by comparing the test results, the finite-element method and the proposed semiempirical
formulations for the same breaking load.

The aim is to understand the causes of these anomalies and suggest possible solutions without disclosing the specic names of the buildings or the products involved.

The work underlines the importance of having standard test procedures used to determine the stone properties employed in the design and dimensioning of prestressed panels. A case-study using 2 types of stones (granite and limestone) is presented to exemplify the application of the stone characterisation under the scope of the technical specification. When safety requirements consider the environmental aspects of the application, the design and dimensioning of the panels must consider the decay of the properties evaluated under the corresponding natural stone specification.

Experimental studies on the behaviour and performance of prestressed natural stone hollow panels ... more Experimental studies on the behaviour and performance of prestressed natural stone hollow panels were performed using prestressing wires as internal tendons to apply a compression force to pre-assembled dimension stone slabs forming the panels. Six prototypes were subjected to three-point bending and vibration tests, and the effect of filling the panel void with polyurethane and of the prestressing intensity was also studied. Dynamic tests were performed to obtain the panel's self natural period of vibration and the natural stone's Young's modulus. Static load tests were performed to ascertain the panels' suitability for application as stand-alone façade panels. The experimental results revealed two distinct failure modes after cracking, depending on whether polyurethane infill was injected into the void. The postrupture behaviour was analysed taking into account the favourable effect of filling the panel void with polyurethane foam. Finite element computer analyses of the stress states induced in the panels were also carried out for three different geometries. Data obtained from specimens subjected to the same load regime were compared.

They must accommodate hygrometric differential movement, deflection, vibration and creep, etc. When available, code requirements do not provide an accurate or realistic safety factor for the specific type of anchor and or stone used in a project. Global safety factors that are recommended by stone industry associations are imprecise and used as rules of thumb. Limit state design has replaced the older concept of allowable stress design in most forms of civil engineering. As a result, all modern buildings are designed in accordance with a code which is based on limit state theory for all man-made materials, yet there is an astonishing nonexistence of ′natural stone′. In this paper partial factors of safety are proposed depending on the types and on the coefficients of variation of the distributions of resistances. Their values are determined using stru...

Two limestone and various marble specimens were submitted to a series of tests – namely standard absorption, bulk specific gravity and flexural strength tests – to determine their physical and mechanical properties. The paper focuses on the results of tests carried out according to the ASTM Standard Test Method for Strength of Individual Stone Anchorages in Dimension Stone. These tests were performed on a stiff rail continuous anchorage system on both the front and rear kerf legs. Stress analysis and finite element method calculations were the basis for the proposed semi-empirical formula to estimate this anchorage system's breaking load under the above-mentioned conditions. Through a general but practical example, it is shown that a design focused on the bending strength of stone panels, to the detriment of the kerf anchorage, is an unsafe and yet common practice. The paper emphasises that design...

The presented methodology does not introduce any difficulty of application since it simplifies the establishing of cash flows with the introduction of the concept of equivalent time allowing the appraiser to obtain sustainable values based on the real estate market rates. The goal is to address an easy to use more precise tool to find an appraisal value via the so-called Cost Method.

The 33 chapters of the handbook have been written by 66 contributors. They have presented their material in a ready-to-use form with flowcharts to show step-by-step procedures wherever possible. Therefore, derivations of formulas are omitted in all but a few instances, and many worked-out examples are given. Background information, descriptive matter, and explanatory material have been condensed or omitted. Because each chapter treats a subject that is broad enough to fill a book by itself, the contributors have had to select the material that, in their judgment, is likely to be the most useful to the greatest number of users. References and sources of additional material are noted for most of the topics that could not be treated in sufficient detail.
The constant search to maximize the transparency of the façades resulted in larger glass windows forcing concrete and steel load-bearing systems to become smaller over time.

External cladding of buildings was regarded, along the last decades, as an aesthetic “well-regarded” solution with no need for relevant maintenance works and costs.
Natural stone-clad façades make a significant contribution to the overall aesthetic and technical performance of a building. They have a substantial effect on people’s judgment about visual impact, yet they submitted to a variety of actions such as heat, air, and moisture actions or dynamic loadings such as wind and seismic effects.
Durability, environmental compatibility, and economic sustainability along with mechanical, chemical, thermal, hygrometric, and other weathering “actions” are the key aspects that must be addressed together with the strength and structural safety.
Several methods or systems are available for installing stone on the exterior of buildings depending on the manner how the environment and exposure conditions are addressed. Temperature changes, air pressure, water, in any form, as direct or indirect induced tensions must be undertaken appropriately, based on a robust empirical investigation encompassed with lessons from older thin-stone cladding building’s façade systems.
Under the structural point of view, numerous techniques were employed to support the stone panels, both within curtain walls as well as individually. The development of curtain wall systems, consisting of vertical and horizontal structural members, connected and anchored to the supporting structure and the notable stones’ cutting technology provides all the normal functions of a curtain wall, using thin cladding slabs or panel as its skin. Figure 33.1 is an example of a curtain wall system providing a ventilated façade.
Façade veneer systems must comply with structural safety requirements in particular for direct actions such as the inertial forces on heavy stone cladding panels that are more susceptible to earthquake damage. In some regions, wind action acting in lighter panels may be more stringent than seismic action. Stone cladding failure can induce serious injury to people and may cause relevant financial losses.

When subjected to tensile stress, glass break with any plastic flow because it is a brittle material. The break occurs at a stress level much lower than the theoretical value calculated from the strength of the atomic bonds. The glass is unique since its fracture occurs in entirely different ways from other materials. Glass failure generally starts at a specific surface flaw which is as a stress multiplier in a region of high tensile stress.
Failure prediction methods based on allowable areas for each thickness of glass as a function of uniform duration pressure have been replaced by modern methods that have the advantage of providing a consistent framework for all previous testing as also explains most of the phenomena associated with laterally loaded thin glass plates ...
É ainda merecedora de destaque, pelo seu significado e relevância, a preocupação didáctica manifestada pelo autor, ao incluir exemplos práticos de aplicação dos diferentes temas tratados ao longo do livro, o que constitui uma significativa mais valia da obra em apreço, desde logo para os estudantes dos cursos de engenharia, mas também, seguramente, para os profissionais envolvidos no projecto de fachadas envidraçadas.
A temática abordada – comportamento estrutural de fachadas envidraçadas - a que acresce o rigor científico e técnico com que é tratada, tornam este livro, caso único em língua portuguesa, uma obra de consulta obrigatória para todos quantos se dedicam ao projecto e construção deste importante elemento construtivo.
Inscrevendo-se, claramente, pela sua natureza, no campo da engenharia, o presente livro não deixa de constituir, por esse motivo, uma obra igualmente útil para estudantes e profissionais de arquitectura, que aqui encontrarão ampla e detalhada informação que em muito os auxiliará na concepção e desenho de fachadas envidraçadas.
dimension stone cladding of rainscreen fac¸ades. Based on a number of mechanical tests using various types of
Portuguese stone – three igneous, two sedimentary and one metamorphic – a study was carried out to investigate the
relationship between the flexural strength and breaking load of specific and very common stone types. Several
physical and mechanical characterisation tests and 130 pull-out tests with 6 and 8 mm cone bolt threads were
performed to determine the pull-out load failure on six different stone types: three granite, two limestone and one
marble. Finite-element stress analyses were carried out, and the test results were the basis for calibrating a simple
formula that can be used to estimate the stone’s breaking load at the undercut anchorage. Stress concentration
factors are proposed to take into account the undercut drill hole geometry and the specific properties of each type of
stone. Stone specimens from the same batches were subject to pull-out force tests using dowel anchorages, whose
values were then compared with the breaking load of undercut anchorages. Results are discussed and conclusions are
drawn based on tensile stress values by comparing the test results, the finite-element method and the proposed semiempirical
formulations for the same breaking load.

Based on the traditional real estate appraisal methodologies the so called comparative approach technique is presented to support on the relative most adding value decision for buy or sell a real estate unit. A study case is presented to clarify this appraisal method.
Os prazos ou duração para a realização das partes e formação dos valores que compõe os custo são considerados, havendo assim que considerar, no lugar da ``margem'', uma taxa de actualização.
A forma como se estabelece a formação do presumível valor de transação, resulta de somar os custos actualizado por essa taxa e considerando que cada parcela do custo ocorre de uma vez num dado instante após o início do projecto.
Esta simplificação, pretende substituir uma abordagem dinâmica com recurso à actualização de ``cash-flows'', pelo que se designa por pseudo-dinâmica.

In this paper, we present a different approach to what is usual for the real-estate appraisal using the so-called ``Cost Method''.
Duration and timelines for values that make up the cost and margin need to be regarded and so the implicitly return rate as well.
In a simply manner the problem is addressed -- the pseudo-dynamic approach.
Keywords : Appraisal, Cost Method, pseudo-dynamic approach.
São apresentados os procedimentos necessários da adaptação desta norma à regulamentação europeia.

Abstract
In this paper we present the main aspects related to the time value of money. A special reference to the annualization of values is done in order to allow establishing comparisons between mutually exclusive projects.
Keywords: Capital, interest rate, Investments
The comparison is made with a safety measuring parameter, the ratio between the ultimate applied force, and the initial force .The results obtained allow to conclude that bond and compression substantially increase the ultimate bearing capacity.
In the case of glazing façades particular attention must be paid to excessive deformation at the profiles in order to avoid glass breakage which may cause person's injury(ies) or property damages.
Following the recommendations of the American Standard ASTM E1300 different deformation limits are considered either in a serviceability limit state or at ultimate limit state condition.
Keywords: Façade design, aluminum profiles, glazing.
A utilização de fachadas pressurizáveis constitui uma tecnologia de construção cujo principal objectivo consiste na redução do gradiente de pressões entre o exterior e a caixa de ar inimizando, tanto quanto possível, a entrada da chuva batida pelo vento na caixa de ar.
Esta técnica é, em Portugal, praticamente desconhecida, pese embora o facto de se encontrar em franco desenvolvimento nalguns países onde existe experiência e investigação com resultados comprovados.
Passam-se em revista as diferentes configurações que possibilitam a infiltração da humidade e da chuva e analisa-se a distribuição da pressão do vento e trajectórias da água nas fachadas. Enquadram-se as fachadas pressurizáveis nas diferentes estratégias de protecção da envolvente. Explicam-se os princípios associados aos sistemas de fachadas com caixa de ar pressurizável.
Estabelece-se uma metodologia de abordagem para o estudo e
dimensionamento de fachadas pressurizáveis tendo em conta a
modelação da acção do vento e os mecanismos associadas à
auto-pressurização em fachadas.
Apresenta-se uma formulação analítica para os fenómenos físicos
associados à compensação de pressões. Indicam-se alguns parâmetros
de forma a minimizar o diferencial de pressões entre a caixa de ar e
o exterior. Apresentam-se alguns exemplos para vários sistemas de
fachada cortina pressurizáveis.
São descritos os princípios orientadores para um desempenho
eficiente das fachadas com caixa de ar auto-pressurizável.
