摘要
介绍了钢桁架结构体系的布置特点,结合初始态张拉分析,提出合理运用张拉预应力的方法。考虑初始缺陷,着重进行几何非线性分析和弹塑性极限承载力分析,找出结构的破坏机制。计算结果表明结构具有足够的安全储备。
The roof of the gym is a typical pre-stressed steel truss. It mainly introduced the structure layout. With initial pre-stress and static analysis, the effective method to use the pre-stress was given. Considering initial imperfection, the geometry nonlinear calculation and elastic-plastic ultimate load capacity analysis are taken, and then the damage mechanism was got. The results show that the structure has enough safety emergence capacity.
