Abstract

Reinforced Concrete (RC) framed buildings with clay masonry infills represent a very common structural typology worldwide. Infills are commonly considered as partition elements without any structural function nevertheless their role is crucial in terms of global and local response of RC buildings in the event of earthquake, and, therefore, their behaviour under seismic actions should be reliably characterized. One of the first issues to face with is related to a proper numerical modelling to reproduce the influence of infills on the global behaviour of RC frames under seismic actions. Some models have been already proposed in literature, but their reliability should be yet proved on the basis of an as huge as possible experimental database. Therefore, in this paper, a homogenous extensive database of experimental tests on RC frames infilled with hollow clay-masonry infills – typical of Italian RC building stock – is collected and presented. The experimental response of masonry infills under lateral loads is obtained. The main numerical models existing in literature for infills are investigated and compared with the experimental results in order to select the model that minimize the prediction error or propose a modification of the existing models.
