摘要
联合格构式构架在多向风荷载作用下的受力情况不同,有必要对各方向风荷载作用下的格构式构件的应力应变进行分析,比拟出控制工况用于实际工程设计分析。使用三维空间有限元模型,定义合理的钢材本构关系,分析不同风向作用下格构式构架的力学性能,从而得出格构构架的柱脚节点反力和构架应变,确定满足工程设计需要的计算结果。
under multidirectional wind load, mechanical properties of united laced frame is different . It is necessary to analyze the stress and strain of laced frame under multidirectional wind load, and get analogue result to apply to practical engineering project. This article use 3-D space ifnite element model, deifne right constitutive relationship of steel, analysis mechanical properties of laced frame. Thereby, pick out pedestal reaction and frame strain and determine result to satisfy the requirement of project.
