| 摘 要： | 采用计算机模拟仿真方法,对空间钢管-板XX型节点进行参数分析。研究了不同的支管加载比例、几何参数和主管应力比对空间钢管-板XX型节点的破坏模式和极限承载力的影响。结果表明:节点板间的夹角不同时,支管加载比例对节点极限承载力的影响规律有很大差异;主管应力比无论正负均会引起节点极限承载力的降低。在此基础上,通过对数值结果的回归分析,考虑了节点板间的夹角和支管加载比例的空间影响效应,提出适用于该类节点的极限承载力公式。

| Abstract: | A parametric analysis was carried out to investigate the gusset plate to CHS XX joints with the finite elements method. The effects of web loading proportion, geometric parameters and axial stress in chord on the failure modes and the ultimate strength were employed. It is found that the web loading proportion have different effects on the ultimate strength with different angles between two gussets. And the ultimate strength of joints decreased no matter the axial stress in chord was positive or negative. Based on the regression analysis, a formula was proposed for predicting the ultimate strength of the gusset plate to CHS XX joints. |
