摘要
本文首先简要叙述了半刚性连接节点的特性;其次介绍了推导局部坐标下的单元刚度矩阵的过程及如何对半刚性连接单元的固端力进行修正,并对刚度矩阵进行了高精度改造;最后讨论了弹塑性阶段半刚性节点的简化方法。
The article introduces in brief the features of semi-rigid connection at first, and then introduces the process that the element stiffness matrix under local coordinate system is derived, puts forward how to correct the fixed end force of semi rigid connection unit, and gains the stiffness matrix for the high preci-sion. Finally the article discusses the simplified method of elastic-plastic stage of semi-rigid nodes.
