摘　　要：拱支网壳结构体系是在综合了网壳(网架)及拱结构等优点的基础上,构思出的一种新型大跨度空间杂交结构形式。本文根据所确定的结构分析模型,结合现有理论,建立了大跨度拱支网壳结构的弹塑性分析理论,并编制相应的结构分析程序。Based on the structural features of reticulated shells, arch structures, etc., the arch supported reticulated shell structures have been developed as a new large span space structural system. In the paper, typical structural models of the hybrid system are presented. Then the elasto plastic large deformation analytic theory is founded and the corresponding program using FORTRAN language is achieved. Finally, numerical examples are analyzed by the program, which proves the correctness of the analytic theory and the effectiveness of the program. [
