| 摘 要： | 本文给出了具有半刚性梁柱节点连接框架梁的弯矩转角位移方程。按此方程导出了无侧移框架和有侧移框架柱的计算长度取值方法。该方法与我国规范规定的计算长度取值协调一致,不过考虑半刚性连接时要对横梁的约束刚度进行适当的修正。

| Abstract: | Moment slope displacement equations of beams with two end semirigid connection restraints are covered. The evaluation of column effective length factor both braced frames and unbraced frames with flexible joints is derived. Determination of column effective length method proposed herein is. exactly the same as those of rigid frames which was well established in Chineses Specification of Steel Structures, however, the restraining stiffness of girders to columns should be amended semirigid connection is applied. |

| Keywords: | semi-rigid connections frameworks column effective length |
