Despite a number of analytical models, trying to describe the processes of damage accumulation in the long term, are available, however very few experimental tests have been done, probably because ofthe uncertainties and difficulties on choosing and controlling the leading parameters for the setting up the tests and for interpreting the related results. The present paper describes and comments the experimental tests and results on a number of small scale masonry specimens, with the intent to better understand the effect ofrepeated loads on the masonry strength. The damage accumulation due to repeated loads may lead to a better understanding offailure behavior of old massive masonry, like, for example, bell towers, high ditch walls, where the static capacity is stressed by average heavy load conditions.
