带暗支撑再生混凝土中高剪力墙振动台试验研究
|
摘要
为研究钢筋暗支撑对再生骨料混凝土剪力墙的抗震能力提高的贡献,进行了3个钢筋混凝土中高剪力墙振动台试验研究,包括1个普通钢筋混凝土中高剪力墙、1个全再生骨料混凝土中高剪力墙、1个带暗支撑全再生骨料混凝土中高剪力墙。实测了各剪力墙在弹性、开裂及破坏阶段的动力特性、加速度反应、位移反应和破坏形态,并对其进行了分析比较,结果表明:带暗支撑再生混凝土中高剪力墙在各阶段的位移反应比普通再生混凝土剪力墙明显减小,抗震耗能能力明显提高。
To analyze the effect of concealed bracings to the seismic performance of mid-rise recycled concrete shear walls,the shaking table tests of three models of RC shear wall,including one natural aggregate concrete shear wall and two recycled aggregate concrete shear walls with or without concealed bracings,were carried out.The dynamic characteristic,dynamic response of acceleration as well as displacement,and failure patterns of three models at different stages were measured and compared.The test results show that the roof drift of a recycled concrete shear wall with conceal bracings was much smaller than that of the recycled concrete shear wall without conceal bracings.And the energy dissipation ability was obviously improved.
