摘　　要：以柔性连接非规则梁在钢框架弹性失稳形态中的受力特性为基础,分析了非规则梁侧移刚度对框架柱计算长度的影响,推导了具有非规则梁的钢框架柱是否需要进行计算长度修正的判定条件。算例表明,本文建议的方法和公式可供工程设计参考使用。Based on the buckling behavior of steel frame column connected with abnormal beams, the influence of abnormal beams＇ sway stiffness on the effective length of frame columns is studied in this paper and deduces the estimated rules for whether need modification of effective length. Numerical example shows that the method and formula suggested in this paper is with satisfied accuracy.
