Abstract: This article is aimed at proposing a numerical model for the study of the monotonous and cyclic behaviour of reinforced concrete frames equipped with masonry infills. In fact, the main purpose of this study concerns to derive a reliable model that is able to predict the monotonic and cyclic response of reinforced concrete infilled masonry frames. To this end, after a critical analysis of the available literature, the authors combine two models, one for the monotone response and the other for the cyclic one, showing their reliability with reference to six different experimental cases. The final step considered in this article is to propose an experimental procedure to minimise the error between the numerical analysis and the results of the six experimental literature tests examined, in order to provide a family of 16 new variables that substantially improve the starting models selected.

Keywords: infilled RC frames; non-structural elements; earthquake damages; macro-models; seismic-behaviour.
