Seismic pounding behavior of multi-story buildings in series considering the effect of infill panels

Abstract

The aim of the present paper is to study the influence of the infill panels on the seismic pounding response of adjacent structures in series. The contribution of the masonry infill has been simulated using equivalent diagonal compression struts. Steel frames have been assumed to have elastic-plastic behavior with 1% linear strain hardening. The dynamic contact analysis has been utilized where contact surface model (target and contactor) has been applied without any connectors between the adjacent buildings. Nonlinear finite element analyses have been conducted on different configurations of infill distribution throughout the structures. The results of the analysis reveal that the existence of infill panels can substantially change the seismic behavior of the structures and may have a serious influence on their behavior during exposure to mutual pounding under seismic excitation. Moreover, the distribution of infill throughout the structure can significantly affect its behavior during earthquakes.
