带混凝土楼板钢梁—钢筋混凝土柱节点抗震研究

Study on steel beam-steel concrete colum joint seismic resistance with concrete floor board

采用ANSYS软件,对影响混凝土楼板组合效应的节点性能因素作了分析,以楼板配筋率、混凝土强度、有效宽度为参数,在梁端进行了低周反复加载,通过有限元模型的验证,分析了节点试件的破坏特征和承载力以及混凝土楼板的有效宽度,得出了一些有意义的结论。

Applying ANSYS software, the paper analyzes factors influencing concrete floor board combined effect joint performance, takes floor reinforced ratio, concrete strength and effective width as parameters, carries out low frequency cyclic loading test on the beam end, carries out the inspection with finite element model, analyzes joint sample damage features, bearing capacity and effective width of concrete floor board, and finally draws some meaningful conclusions.
