Effects of diaphragm flexibility on seismic response of asymmetric-plan buildings

Abstract

Effects of diaphragm flexibility on seismic response of asymmetric-plan buildings The effects of diaphragm flexibility on seismic response of asymmetric-plan buildings are investigated in this paper. The results show that the diaphragm flexibility could induce different effects depending on the asymmetric system characteristics, selected element, level of structure yield, and degree of diaphragm flexibility. When the structure behaves in elastic range, central walls exhibit a significant increase in response, and the situation can further be aggravated by asymmetricity in system. Also, all walls of the structure experience a significant increase in response in nonlinear range, which cannot be ignored.

Methods to Reproduce In-Plane Deformability of Orthotropic Floors in the Finite Element Models of Buildings

“…Moreover, it is not unusual to deal with buildings having high length-to-width ratios [15], in-plan irregular structural patterns, and/or shear walls not uniformly distributed within the building plan [14]. For such buildings, the in-plane floor deformability could determine a larger demand of both strength and ductility to some structural elements as compared to the case of rigid floors [16][17][18][19][20][21][22].…”
