单排配筋L形截面剪力墙振动台试验研究

Shaking table test study on L-shaped shear walls with single layer of web reinforcement

  • 摘要: 为了解配筋形式对单排配筋L形截面混凝土剪力墙在非工程轴方向的抗震能力影响,进行了2个单排配筋L形截面剪力墙模型的振动台试验,1个为普通单排配筋剪力墙,1个为带斜筋单排配筋剪力墙,2个剪力墙模型的总配筋量相同。通过在L形截面剪力墙的非工程轴方向输入El-Centro地震波,测试比较2个剪力墙模型在弹性、开裂及破坏阶段的动力特性、地震反应与破坏特征,分析不同配筋形式下L形截面混凝土剪力墙在非工程轴方向的抗震能力,结果表明,带斜筋与不带斜筋的单排配筋L形截面混凝土剪力墙在非工程轴方向均有良好的抗震性能,能够满足低多层建筑结构的抗震设计要求。

     

    Abstract: In order to investigate the influence of different reinforcement arrangements on the aseismic capacity of L-shaped shear walls with a single layer of web reinforcements along the non-engineering-axis direction, two shaking table tests of L-shaped shear wall models with a single layer of web reinforcements were carried out. One is the shear wall with a single layer of web reinforcements and another is the shear wall with both a single layer of web reinforcements and inclined steel bars. The total reinforecment ratio of two shear wall models is the same. With inputted the seismic wave of El-Centro along the non-engineering-axis direction of L-shaped shear walls, the dynamic characteristics, the dynamic response and failure mode of each model under elastic, the crack and failure stages were measured and compared, also the aseismic capacity of L-shaped concrete shear walls along the non-engineering-axis direction was analyzed. The results show that L-shaped shear walls with inclined steel bars or without both have good aseismic performance along the non-engineering-axis direction and they can meet the aseismic design requirements of low or multi-layer building structures.
