| 摘 要： | 采用SAP2000有限元软件对钢管拱桁架进行非线性静力推覆分析,得出结构性能点水平位移小于结构刚进入塑性时对应的水平位移,说明可以根据提前定义容许准则并分析结构性能点的行为,判断设计目标是否满足抗震性能要求。

| Abstract: | Using SAP2000 finite element software,this paper conducts nonlinear static pushover analysis of steel tube arch truss,and concludes that the horizontal displacement of structural performance point is less than the corresponding horizontal displacement when the structure just enters plasticity.The conclusion shows that it is possible to judge whether the design objectives meet the seismic performance requirements by defining the allowable criteria in advance and analyzing the behavior of structural performance points. |
