摘要
随着对梁柱节点性能研究的深入,发现连接性能对结构性能有着很大的影响,同时在进行结构柱构件稳定计算时必须考虑柱端约束条件,因此需要将柱端连接性能的影响反映到约束条件中去。现有规范并未就如何考虑连接半刚性性能对柱构件计算长度的影响作出可供直接采用的计算方法。结合规范的制订依据提出了考虑连接性能对柱计算长度影响的计算方法;全盘考虑连接性能对层间整体稳定的影响。
With a deepening research on behavior of beam-column joints,it has been found out that the connection behavior has a great influence on a structural behavior,meanwhile column end constrained conditions must be taken into account when carrying out a stability calculation of the structural column member. Therefore the effect of column end connection behavior should be included in the constrained conditions. In the current specifications there are no direct calculation methods of how to consider the effect of semi-rigid connection behavior on a column effective length. According to the basis for working out a specification it is proposed a method of how to consider the effect of the connection behavior on column effective length, and the one to consider the effect of connection behavior on the interlayer integral stability.
