【 摘 要 】

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 asymmetric system characteristics. Also, all walls of the structure experience a significant in+crease in response in nonlinear range, which cannot be ignored.
