摘要
通过在PMCAD中建立简单模型对较大跨度坡屋面空间折板（带腋梁）结构进行模拟，并利用SATWE、PMSAP空间有限元分析软件对之进行受力分析，为紫园别墅坡屋面结构设计提供思路。
This paper uses the wide span spatial folded plate （haunched beam） structure to simulate pitched roof by a simple model builded in PMCAD, and analyses the space stress of folded ？ plate structure by utilizing such finite element programs as SATWE, PMSAP. At last, some design suggestions related to pitched roof of villa are proposed.
