摘要
柱计算长度法是钢框架稳定设计的常用方法,顶底角钢连接梁柱节点是一种典型的半刚性梁柱节点。采用抗弯弹簧模拟梁柱节点连接的半刚性,考虑梁柱间的相对转角关系,通过引入梁柱线刚度比修正系数的计算方法,得到顶底角钢半刚接钢框架柱计算长度系数的修正公式。
Effective length is an usual method in steel frames stability design, and top and seat angle node is a typical semi-rigid node. The modified factor formulas, which are applicable to the top and seat angle semi rigid connected steel frames, are derived by the joint relative rotation under consideration and by the modified stiffness factor, the semi-rigid connection is simulated by a rotational spring.
