无侧移失稳半刚接钢框架柱计算长度系数研究

摘要

According to the forms of beam no-sway buckling,the paper adopts the semi-rigid spiral spring simulation nodes,considers the mutual influence when the node semi-rigid features and the various stiffness of the nodes of the column＇s two sides,leads the connection relative flexibility u and the partition coefficient of relative angle of beam columns α,and concludes the calculation formula for the stiff correction coefficient of beam lines β,and indicates the formula for the calculation of length of the semi-rigid steel frame columns.%按照梁无侧移失稳形式,采用螺旋弹簧模拟节点的半刚性,考虑了节点半刚性及柱两侧节点刚度不同时的相互影响,引入了连接相对柔度u和梁柱相对转角的分配系数α,得到了横梁线刚度修正系数β的计算公式,进而得到了半刚接钢框架柱的计算长度系数公式。
