dc.description.abstractThe masonry infill walls are widely spread over the reinforced concrete buildings due to different demands. The buildings' thermal energy efficiency is a top priority nowadays since many of the existing building stock comprises buildings with low energy performance. The buildings' external envelope is suffering a transformation with the appearance of the vertical hollow concrete blocks with high thermal and acoustic demands. However, recent evidence from a strong earthquake shows that the masonry infill walls are vulnerable to out-of-plane loadings and were responsible for many casualties, injuries, and economic losses. Based on that, this work's main objective is to study the out-of-plane (OOP) behaviour of masonry infills made with vertical hollow concrete blocks. The experimental campaign comprises the OOP testing of three full-scale infill walls made up of these masonry units. One of them was as-built without previous damage, one with previous damage due to an earlier in-plane test and the third one retrofitted. All the tests consisted of applying the loading-unloading-reloading history of imposed displacements in the OOP direction through a uniformly distributed load. The results will be presented in terms of OOP force-displacement responses, deformed shapes, damage evolution, energy dissipation capacity and damping. Finally, the test results are compared to each other to assess the previous damage and the retrofit technique's effectiveness.eng
