【摘要】 轴压比是剪力墙抗震设计中一个重要的控制因素,它直接关系到剪力墙的抗震性能。简要介绍了钢筋混凝土剪力墙和型钢混凝土剪力墙抗震研究的有关成果,重点介绍了轴压比对剪力墙抗震性能的影响。进行了3个1/3缩尺的剪力墙的抗震性能试验研究,包括1个普通混凝土剪力墙、1个内藏钢框架混凝土组合剪力墙和1个内藏钢桁架混凝土组合剪力墙。试验表明:在高轴压比情况下,内藏钢框架、内藏钢桁架混凝土组合剪力墙的抗震性能比普通混凝土剪力墙明显提高。更多还原

【Abstract】 The axial compressive ratio has always been a vital element in design relating to seismic behavior of a shear wall.In this paper,some achievements have been briefly introduced about seismic behavior of a reinforced concrete shear wall and a steel reinforced concrete shear wall.The influence of the axial compressive ratio on seismic property of the shear wall is emphatically introduced.The experimental study on the seismic behavior of three 1/3 scale shear walls,including a shear wall with steel frame,a shear wall with steel truss and a usual one,has been studied.The experimental results show that,compared with the usual shear wall,the seismic behavior of the shear wall with steel frame and the shear wall with steel truss has been observably improved under high axial compressive ratio condition.更多还原
