【摘要】 型钢混凝土短肢剪力墙是一种新型的剪力墙结构形式,它可以充分发挥钢和混凝土两种材料的优势,改善普通钢筋混凝土短肢剪力墙延性和耗能能力较差的缺点,其抗弯、抗剪承载力和抗震性能均好于后者。文中对3个1/2缩尺的型钢混凝土组合"一"字形短肢剪力墙进行了低周反复荷载下的抗震性能试验研究,墙肢截面宽厚比分别为5、5.5、6。在试验研究基础上,分析了各剪力墙承载力、延性、滞回特性及破坏特征,并提出了抗震设计建议。试验结果表明型钢暗柱的存在提高了混凝土短肢剪力墙的后期强度储备,改善混凝土短肢剪力墙的抗震性能。更多还原

【Abstract】 Shape stee1 reinforced concrete short-leg shear wall is a new kind of short-leg shear wall.It can take full advantages of steel and concrete,of which flexure,bearing capacity,ductility,ability of dissipating energy and seismic behavior is better than the traditional reinforced concrete short-leg shear wall.In this thesis the experimental studies on the seismic behavior of three 1/2 scale shape steel concrere short-leg shear walls with three wall width-depth ratios(5,5.5 and 6)have been made.Based upon the experimental study,bearing capacity,ductility,hysteresis property and failure phenomena of each shear wall are contrastively analyzed,and suggestions of anti-seismic design of the shape steel concrete short-leg shear walls are presented.The results show that owing to the setting of the concealed steel columns in the short-leg shear wall,the late strength reserve of the shape steel concrete short-leg shear wall has been increased greatly and its seismic behavior has been improved obviously.更多还原
