摘　　要：对张弦网壳结构地震响应规律进行大量理论分析与计算研究。在建立多自由度体系计算模型及地震响应基本方程的基础上,探讨对比采用不同计算方法、不同方向单维地震作用及多维地震作用下张弦网壳结构的地震响应,深入地研究张弦网壳屋盖与下部支承体系的静力及动力相互作用,强调采用整体模型的必要性,并给出张弦网壳结构地震响应的特点与规律,从而对张弦网壳结构的抗震设计提出有益的建议。The theoretical analysis and computing research on seismic response analysis of latticed shell with tension chord are presented. Based on the multi-degree freedom calculation model and fundamental equation of seismic response, the seismic responses of latticed shell with tension chord in different calculation methods, one-dimensional and multi-dimensional earthquake in different directions are compared. The static and dynamic interaction of the shell roof and bottom supporting structure is in-depth studied and the necessity of integral model is emphasized .The characteristics and regularity of seismic response of latticed shell with tension chord shell are also presented. Which provides useful suggestions for the seismic design of latticed shell with tension chord.
