摘要:
为改善低矮剪力墙的抗震性能,设计了一种空腔剪力墙.分析了配筋的普通剪力墙、开暗缝剪力墙和空腔剪力墙在侧向荷载下受力特点的差异,建立了空腔剪力墙的理论计算模型,推导了空腔剪力墙在侧向荷载作用下的等效抗侧刚度和内力的计算公式,并对影响空腔剪力墙刚度的各参数进行了探讨,研究了各参数的影响规律.结果表明,空腔剪力墙降低了构件刚度和承载力,提高了延性,通过改变空腔的参数,可实现剪力墙刚度、承载力和延性的合理匹配.不同参数的模型验证结果表明,理论计算公式误差在15%以内,可满足工程估测需要.对于低矮剪力墙,通过合理改变空腔的长度和厚度,不仅可以降低自重,还可以较为显著地降低剪力墙刚度,从而达到减小地震作用的目的.
Abstract:
To improve the aseismic performance of the shear wall with the low aspect ratio, a cavity shear wall was designed. The difference of the mechanical characteristics among the common shear wall, the shear wall with concealed vertical joint and the cavity shear wall under the lateral loads was analyzed. The theoretical calculation model of the cavity shear wall was built. The calculation formulas of the equivalent lateral stiffness and the internal force of the cavity shear wall under lateral loads were deduced. The parameters influencing the stiffness of the cavity shear wall were discussed, and the influence rule of each parameter was studied. The results show that the stiffness and the bearing capacity of the cavity shear wall is reduced and the ductility are improved. The reasonable matching among the stiffness, the bearing capacity and the ductility can be realized by changing the parameters of the cavity. The verification results of the models with different parameters show that the errors of the theoretical calculation formulas are less than 15%, which can meet the needs of engineering estimation. For the cavity shear wall, by changing the length and the thickness of the cavity reasonably, both the weight and the stiffness can be significantly reduced so as to reduce the seismic action.
