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-of-plane out-of-plane stability of the light-weight, lattice-structured rigid frame with a triangular cross section is an issue that must be considered in design. Starting from the analysis of the whole process of the structure, considering the geometrical nonlinearity, after a great deal of computer analysis, the overall stability of this kind of structural system has been studied, and through the summary of the obtained data and the comparison with the equivalent real belly frame , Put forward a simple and feasible method of stable checking.
