梯形钢屋架静动力分析

摘要

在ANSYS环境下采用弹性分析建立有限元模型对屋架进行静力和水平地震波作用分析，对其在静力作用下进行了内力及变形的分析，同时，对其在水平地震波作用下的最大位移进行了分析并得出一定的结论。%This paper sets up finite element model by using elastic analysis under ANSYS environment and analyzes the static force and horizon- tal seismic role of the grid roof, and analyzes the internal force and deformation under statistic force, simultaneously analyzes maximum displace- ment under horizontal seismic wave, and then draws some conclusions.
