某钢网架静力载荷试验及数值模拟分析

Static Loading Test and Numerical Simulation Analysis of a Steel Space Truss

某工程因装修改造,需对该工程钢结构网架下弦面增设吊顶,增加荷载。论文通过对该钢结构网架进行现场静力载荷试验及数值模拟分析,并对试验结果与模拟结果进行了对比分析,从而确定数值模拟分析的可靠性,最终确定增加吊顶荷载后网架杆件应力及节点竖向位移变化情况以及结构安全性。

Due to the renovation of a project,the ceiling should be added to the lower chord of the steel structure grid to increase load.In this paper,the static loading test and numerical simulation analysis of the steel space truss are carried out,and the test results are compared with the simulation results,so as to determine the reliability of numerical simulation analysis,and ultimately determine the changes of the bar stress and node vertical displacement and structural safety after increasing the suspended ceiling load.
