摘要
截面为三角形的轻型空间格构式刚架的平面外整体稳定性是设计中必须考虑的问题。从结构的全过程分析着手 ,考虑几何非线性 ,经过大量的计算机分析 ,对这种结构体系的整体稳定性能进行了研究 ,并通过对所得数据的归纳和与等效实腹式刚架的比较 ,提出了一个简便可行的稳定验算方法。
The out plane whole stability of light gauge space latticed frame with triangular section must be considered in design Based on the whole deforming path analysis considering the geometrically non linear problems and through large quantities of computer analysis,the stability behavior of this structure is studied According to analysis of obtained data and comparison with the equivalent solid web frame,a simple and feasible stability check method is proposed
