摘要
本文对于设置了支撑的框架结构，并且节点是柔性连接时的稳定性问题进行了研究。同时给出了在此种条件下的阈值刚度和柱子的计算长度系数的表达形式。这样可以更加合理地区分有侧移和无侧移框架。通过与刚性连接情况的比较，定量地分析了柔性连接的影响。
Considering the flexible connection of joints, the stability of frames with braces has been studied in this paper. Meanwhile, the formulas for the brace threshold stiffness and the effective length factor under these conditions are also given. According to these results, the sway frames and frames without sway can be distinguished more rationally. In comparison with the condition of rigid connection, the influence of flexible connection has been analyzed quantitatively.
