浅谈大跨度屋面结构建模分析

摘要

According to an engineering of gymnasium of grid structure,the discussion is carried out on simplifying establishment of PKPM finite element model. And then the equal rigidity substitution is used to simplify establish-ment,calculation and analysis of model. The study showed that the method is realistic.%以某体育馆工程网架为例，对PKPM有限元软件模型的简化建立与分析进行了探讨，提出采用等代刚度梁法对网架部分进行简化建模参与结构的整体计算分析，通过计算分析表明此种方法较为符合实际。
