摘要
分析了体外预应力空间双弦结构的受力特点 ,建立了几何非线性有限元分析计算模型 ,并编制了相应的计算程序。通过计算结果与试验结果的比较 ,表明计算模型合理 ,程序计算精度良好 ,可用于对该类结构的非线性分析。
The mechanical characteristics of an external prestressed 2 chord spatial steel structure are analyzed The geometric nonlinear finite element analysis model of the structure is established and the computer program is accomplished The calculating results and the test results are compared,which shows that the calculating model is reasonable and the computer program can be used to analyze the structure with good precision
