dc.description.abstractThe seismic assessment of Reinforced Concrete (RC) buildings with Two Leaf Cavity Wall (TLCW) masonry infills requires reliable and computationally efficient numeric models. The current study has two main goals. First, to understand the contribution of TLCWs to the nonlinear response of RC buildings subjected to dynamic excitations. Second, to investigate the efficiency and accuracy of continuum-based Finite Element Modelling (FEM) approaches and simplified, structural Discrete Macro Element Modelling (DMEM) approaches in predicting the ultimate behavior of RC buildings infilled with TCLWs by performing pushover analyses. A half-scaled two-bay, two-storey RC building prototype infilled with TLCWs, experimentally tested on a shake table and already numerically investigated in the literature by FEM approaches, is considered with these aims. The responses of the FEM and DMEM models are compared to experimental observations in terms of pushover capacity curves and damage patterns. The analyses confirm the ability of the models to effectively predict the lateral deformability and lateral strength of the prototype with a satisfactory level of accuracy. However, some differences are observed in terms of the building's ultimate lateral strength, attributed to the effects of the boundary conditions at the base of the table, not explicitly described by the numerical models. The emphasis is given to the boundary conditions reached during the excitation of the scaled structural system via shaking table. Finally, in the last part of the paper, parametric analyses are performed on the DMEM model to evaluate the main material parameters governing the response of the building effected by the boundary conditions.en_US
