【摘要】 新型混凝土叠合式墙板与周边构件的横向、竖向连接处,由于其有效截面面积较小,会对墙板的承载力和变形性能产生影响。为此,对横向连接处为插筋构造、竖向连接处分别为暗柱和水平筋构造的2片混凝土叠合式墙板进行水平低周反复加载试验,分析结构的破坏形态、延性、刚度、耗能等,并与普通钢筋混凝土墙板做对比。研究结果表明,横向和竖向连接对构件的承载力影响较小,但横向连接会降低墙板的整体变形性能。更多还原

【Abstract】 In view of the horizontal and vertical connections of a new concrete superimposed wall panel,the bearing capacity and the deformation performance of the wall panel may be affected since the area of effective section at the connections is smaller than the wall panel.Cyclic loading tests for two superimposed wall panels which have the horizontal connections with dowel bar and the vertical connections with embedded column and horizontal bars are carried out respectively.The characteristics of failure,ductility,stiffness and energy dissipation are analyzed for each panel,and the comparisons with conventional reinforced concrete wall panel are also presented.The results show that the influence of the horizontal and vertical connections on the bearing capacity is small,but the horizontal connections may reduce the overall deformation performance.更多还原
