摘　　要：介绍了福州市东部新城商务办公中心区C,D座塔楼及超大跨连体结构设计,并分别从构件内力、截面、连体刚度、经济性,整体协调性等多方面,对比分析了底部支承方案、底承顶吊方案、整体空腹桁架方案及整体支承方案四种连体设计方案,提出“巨型双腹板H形截面构件”的连体结构设计概念,选择合理的连体结构形式,为类似结构设计提供参考。The structural designs of C and D tower buildings and the super large-span connected structure in the business center of Fuzhou East New City were introduced.Four connected design schemes bottom support scheme,bottom cap lifting scheme,integral vierendeel truss scheme and integral support scheme were compared and analyzed from the perspectives of internal force,cross-section,connected body stiffness,economy and overall coordination.The design concept of connected structure of mega double-web H-typed cross-section member was proposed,and the reasonable connected structural form was selected,providing reference for similar structural design.
