  • When the mode superposition method is applied to the seismic responses analysis of large-span spatial structures,several problems always become difficult to handle,such as the inefficient calculation and the incapable consideration of earthquake random property. To solve the problems,the seismic response components of large-span spatial structures,including the quasi-static components and resonant components were studied and defined. Based on the seismic response component research,a modified strategy for the mode superposition method of seismic responses of large-span spatial structures was proposed. Through numerical analysis of two typical shell structures, the characteristics of the quasi-static responses and resonant responses and effects of correlation between two components were studied. The distribution features of each response component of large-span spatial structures were summarized.
