ABSTRACT
This chapter focuses on the comparison between experimental test data on masonry building specimens with rigid diaphragms and the results coming from nonlinear analyses on equivalent-frame macro-element models. The models also account for the floor out-of-plane stiffness, by means of equivalent beam elements representing the portion of the floor slab collaborating with the in-plane response of the walls. Pushover and dynamic analyses have been carried out in order to simulate the experimental response. The damage pattern at the end of each numerical dynamic analysis has been reloaded before running the subsequent test. Sometimes, by the comparison of the curves, the strength and stiffness parameters of the model could be updated. In terms of initial stiffness, hysteretic behaviour, strength and displacement capacity, it is important to notice a general good agreement with the experimental results, in all the tests with the exception of the last test.
