【摘要】 通过四片钢筋混凝土剪力墙试件在低周反复荷载作用下的试验,对不同轴压比和不同配筋形式的试件的破坏形态及破坏机制、耗能能力、延性性能等进行了对比研究。试验表明随着轴压比的增大,剪力墙的承载力增大,但同时延性和耗能减小,抗震性能降低;下部配有斜向对角腹筋的剪力墙的耗能要稍高于普通剪力墙,斜向钢筋的存在对阻止底部的剪切滑移起到了作用。更多还原

【Abstract】 Based on the experiment of four reinforced concrete walls under low-reversed cyclic loading,this paper studies the earthquake-resistant behavior of reinforced concrete walls with different ratio of axial compression and reinforcement type,such as failure pattern,failure mechanism,energy dissipation,ductility etc.The experiment shows that axial compressive force ratio increases with shear-walls load-carrying ability,but their ductility,energy dissipation ability and earthquake-resistant behavior decrease at the same time,and that the energy dissipation ability of the shear-walls with diagonal bars is better than that of common ones,with diagonal bars to resist shear slip on the bottom of the walls.更多还原
