【摘要】 为了解决T形短肢剪力墙承载力、延性不对称及在腹板受压时破坏为脆性的问题,提出了型钢短肢剪力墙的概念,即在腹板端部设置型钢暗柱.通过低周反复荷载试验揭示了型钢短肢剪力墙的破坏形态.试验结果表明:型钢短肢剪力墙的承载力和延性有显著提高,适当配置型钢后滞回曲线接近对称,构件的综合性能得到明显改善.更多还原

【Abstract】 The failure of T shaped short-limbed shear wall is brittle when flags are tensile in eccentrically compression,bearing capacity and ductility show differences when push and pull are compared.In order to enhance the seismic behavior of this structure,we set section steel on web.It is a new type of steel-concrete composite member—steel reinforced concrete short-limbed shear wall.Based on the experimental research on steel reinforced concrete short-limbed shear wall under reversed cyclic loading,this paper reveals the failure pattern of T shaped steel reinforced concrete short-limbed shear wall.The result shows that their bearing capacity and ductility which depose a few section steel can be obviously enhanced.The hysteresis curve is approximate symmetry,and these members have good seismic behavior.更多还原
