| 摘 要： | 三角形空间管桁架的平面外整体稳定是工程设计中必须考虑的问题。根据实腹式简支梁的弹性稳定临界弯矩公式,导出三角形空间管桁架梁的临界荷载的简化计算公式,其中包括三角形立体桁架的侧向抗弯刚度、自由扭转刚度和翘曲刚度的等效简化公式推导。在满足工程设计计算精度要求下,提出了一种简便可行的稳定验算方法。

| Abstract: | The out-plane overall stability of triangular space tube truss must be considered in de- sign. According to a formula about the elastic stability of the simple support beam, simplify the formula of critical load of the triangular space tube truss , including torsion rigidity and warping rigidity of triangular spatial tube truss. Under the condition of calculation accuracy, proposed a simple and feasible algorithm. |
