高轴压比下内藏桁架的混凝土组合中高剪力墙抗震性能研究
|
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。该文进行了5个1/3缩尺的轴压比为0.5的中高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剪力墙、1个内藏钢筋桁架混凝土剪力墙、1个内藏钢框架-钢筋桁架剪力墙及1个内藏钢桁架混凝土剪力墙。在试验研究基础上,对比分析了各剪力墙的承载力、刚度及其衰减过程、延性、滞回特性、耗能能力及破坏特征;建立了承载力计算模型,计算结果与实测结果符合较好。试验表明:内藏钢框架及内藏桁架混凝土剪力墙的抗震性能比普通混凝土剪力墙明显提高。
The axial compression ratio has always been a vital element in shear wall seismic design. The experimental study on the seismic behavior of five 1/3 scale mid-rise shear walls with high axial compression ratio were carried out, including a plain shear wall, a shear wall with steel frame, a shear wall with steel bar truss, a shear wall with both steel frame and steel bar truss, and a shear wall with steel truss. For each shear wall, this paper analyzed experimentally the load-carrying capacity, the stiffness and its attenuation, ductility, hysteretic property, energy dissipation and failure pattern. And the formulas of load-carrying capacity were established, whose results were in good agreement with the test results. The experimental results showed that the seismic behavior of the shear wall was improved by the embedded steel frame or truss.
