摘要
从结构的几何非线性分析着手 ,研究截面为三角形的空间格构式斜腿刚架的平面内整体稳定。通过正交设计的方法 ,对常见尺寸范围的格构式斜腿刚架进行了荷载位移全过程分析 ,得到对承载力及计算长度系数影响最为显著的因素 ,并以此为依据通过大量的参数分析给出了便于工程实际应用的斜腿刚架柱的计算长度系数的表格。
Based on the geometric non-linear analysis, the in-plane global stability of Space Lattice Tilted Column Frame of Triangle Section(SLTCF)is studied. Using orthogonal design method, the load-displacement whole deforming path analysis of the SLTCF with common dimensions is carried out. Factors that have very great effect on the in-plane stability loading capacity and the effective-length are obtained. According to lots of parameter analyses, the calculation tables for determining the effective-length of the SLTCF, which is of practical engineering value, are proposed.
