矩形钢管混凝土柱 - 钢筋混凝土梁节点有限元受力性能分析
Mechanical performance analysis of rectangular Steel-tube Concrete Column-reinforced concrete beam joint
摘要
基于高层地下室矩形钢管混凝土柱与混凝土梁节点，提出一种新型连接方式，将梁纵筋与矩形钢管柱钢牛腿焊接，来传递梁端弯矩和剪力。应用 ABAQUS 有限元软件，分析钢牛腿长度，对该节点受力性能的影响。结果表明，钢牛腿长度大于 1.5倍梁高，节点有较好的抗弯能力。本文的研究成果可为工程提供参考。
Abstract
Based on the joints of concrete beam and rectangular steel pipe column in high-rise basement，a new connecting method is proposed toweld the longitudinal bar of the beam and the steel leg of rectangular steel pipe column to bear the bending moment and shera.The length of steel legis taken into account on the bending performance of the joint by ABAQUS.The results show that when the length of steel bracket is more than twicethe height of beam，the joints have better bending capacity.The research may provide the reference for the project.
