【摘要】 介绍了 4片以HRB40 0级钢筋焊接网作为分布筋的矩形、工形和T形截面的中、高剪力墙在反复水平荷载作用下的试验。试件按《建筑抗震设计规范》GB50 0 1 1— 2 0 0 1设置约束边缘构件 ;研究了在中、高轴压比下的剪力墙受弯承载力、变形能力、延性及破坏形态等性能。结果表明 ,剪力墙具有较大的延性和耗能能力 ,为HRB40 0级钢筋用作抗震剪力墙的分布筋提供了试验依据。更多还原

【Abstract】 Experiments of four shear wall specimens with welded HRB400 steel fabric as distributed reinforcement under horizontal cyclic loading are introduced in this paper.The specimens are rectangular section,I section and T section respectively.Boundary zones of specimens are confined according to "Code for seismic design of buildings"GB50011-2001.Behaviors of the shear wall such as bending bearing capacity,deformation capacity,ductility and failure mode under middle and high axial load ratio are studied.The experiment results indicate that shear wall specimens have enough ductility and large energy dissipation capacity.Experimental basis of seismic resistant design of the share wall with welded HRB400 steel fabric as distributed reinforcement are obtained.更多还原
