摘　　要：针对矩形截面组合柱-钢梁节点,结合广东某实际工程,对节点进行有限元数值模拟分析。结果表明,组合节点受力合理,混凝土和型钢能够协同工作,该节点在大震工况下,混凝土局部出现受压损伤,集中在内置型钢交接位置以及柱脚位置;混凝土内钢筋Von-Mises等效应力最大位置集中在柱脚受压侧,绝大部分钢筋尚未进入屈服阶段,节点区域钢材均未达到屈服强度,处于弹性范围内,满足设计要求。此研究能为类似设计提供参考价值。A finite element numerical simulation analysis was performed on the rectangular section composite column-steel beam connec‐tions,using data from an actual project in Guangdong.The findings indicate that the stresses in the composite connections are distributed ap‐propriately,and there is effective collaboration between the concrete and structural steel.Under conditions of severe seismic activity,the con‐crete exhibited localized compressive damage primarily at the interface of the embedded structural steel and at the column base.The peak Von Mises equivalent stress within the internal steel reinforcement was predominantly located on the compressive side at the base of the col‐umn.Notably,most of the reinforcement remained below the yield point,and the steel within the joint area did not achieve its yield strength,thereby staying within the elastic limit and satisfying the design criteria.This analysis can offer valuable insights for the design of similar structural configurations in future projects.
