【摘要】 考虑混凝土楼板后,利用ANSYS分析了梁腹板开圆孔梁柱节点的应力应变分布,节点塑性区的分布及发展过程;比较了在考虑楼板及不考虑楼板情况下,节点受力性能的区别;研究了腹板削弱半径和离柱表距离两参数对节点的影响。分析结果表明,在研究腹板开圆孔梁柱节点抗震性能时,应考虑混凝土板的组合效应。更多还原

【Abstract】 ANSYS finite method was used to analysis stress-strain distribution and their distribution and development of plastic area of the steel moment connections with opening on beam web with concrete slab.The two kinds of connections are compared.The influence between the distance from column and cutting parameter of web-reduced connection was analyzed.Preliminary results show that the effect of composite action should be considered when the seismic performance of steel moment connections is studied.更多还原
