摘　　要：为配合《部分包覆钢-混凝土组合结构技术规程》(T/CECS719-2020)的推广使用,对PEC柱-钢梁组合框架结构进行设计及整体性能分析.介绍了PEC构件的基本概念,并以此为背景设计一个16层PEC柱-型钢梁组合框架结构.利用软件PKPM中的SATWE模块对PEC柱-钢梁组合框架结构的各项性能指标进行分析,并对PEC构件进行验算.结果显示:框架的最大层间位移角为1/529,出现在第9层,小于1/400的限值;结构验算均满足规程要求.PEC柱在竖向荷载及偏心受压荷载作用下不会发生整体失稳,满足极限承载力设计要求.In order to promote the application of "Technical specification for partially encased composite structures of steel and concrete"(T/CECS719-2020), the design and overall performance analysis of PEC column steel beam composite frame were carried out. The basic idea of PEC members were introduced, and on the basis of this background, a 16 storey PEC column steel beam composite frame structure was designed. The SATWE module of PKPM was used to analyze the performance of PEC column steel beam composite frame structure, and the PEC column member was checked according to the technical specification for partially encased composite structures of steel and concrete. The results show that the maximum inter storey displacement angle of the frame is 1/529 in the 9 th floor, which is less than 1/400 of the maximum limit in the technical specification;the structural checking calculation meets the requirements of the technical specification. The results also show that the PEC column will not lose stability under the vertical and eccentric load, which can meet the design requirements of ultimate bearing capacity.
