型钢螺栓连接装配式半刚性梁柱节点弯矩与转角关系研究

Study on the Relationship Between Bending Moment and Rotation Angle of Steel-bolt Jointed Semi-rigid Beam-column Joints

现阶段,新型装配式混凝土梁柱节点的设计与其力学抗震性能的研究是预制装配式混凝土结构的研究热点,但关于预制装配式混凝土梁柱节点的半刚性力学性能研究较少。基于有限元软件ABAQUS对型钢螺栓连接梁柱节点及设计12个可能影响节点弯矩-转角曲线因素的试件进行有限元分析,得到节点与试件的弯矩-转角曲线,通过曲线进一步分析节点的半刚性系数与其他半刚性力学性能。

At present,the research on the design of new prefabricated concrete beam-column joints and its mechanical seismic performance is a hot topic in prefabricated concrete structures,but there are few studies on the semi-rigid mechanical performance of prefabricated concrete beam-column joints.In this paper,based on finite element software ABAQUS,the finite element analysis is carried out on the beamcolumn joints with steel bolt connection and 12 specimens which may affect the bending moment-angle curve of the joints.The bending moment-angle curve of the joints and specimens is obtained,and the semi-rigid coefficient and other semi-rigid mechanical properties of the joints are further analyzed through the curve.
