【Abstract】 The most unfavorable earthquake excitations were investigated,in which geometric non-linearity and material non-linearity were all taken into account.According to the structural dynamic behaviors under different site conditions and seismic waves with different platforms,the relationships between the structural response and site predominant period,as well as platform of seismic wave were built up,by which the most unfavorable earthquake excitations of single-layer spherical shell were obtained.更多还原
