摘要
进行了6个剪跨比为1的超短柱的滞回性能试验研究,其中包括2个钢筋混凝土柱(RC)、2个不设剪力连接件的型钢混凝土(SRC)柱和2个设剪力连接件的型钢混凝土柱.试验结果表明,不设剪力连接件的SRC超短柱的破坏模式为粘结破坏,与RC超短柱相比,其抗剪承载力和变形能力无显著提高,但耗能能力有所提高.设置剪力连接件的SRC超短柱的破坏模式为斜压破坏,与不设剪力连接件的SRC超短柱相比,其抗剪承载力和变形能力显著提高.随轴压比的提高,SRC超短柱的抗剪承载力提高;但轴压比对SRC超短柱的延性和变形能力无显著影响.
Six ultra short columns including 2 reinforced concrete(RC) ultra short columns,2 steel reinforced concrete(SRC) ultra short columns without shear studs and 2 steel reinforced concrete(SRC) ultra short columns with shear studs were tested under combined constant axial compression and cyclic lateral load.The shear span to depth ratio of all the tested columns is 1.The test results show that the failure mode of SRC ultra short columns without shear stud is bond failure;and the shear strength and deformation a...
