介绍了基于位移延性、基于剪力墙顶点位移角限值以及基于塑性转角需求的剪力墙变形能力设计方法的具体计算步骤。利用已有剪力墙试件的试验数据,按照以上三种方法分别计算了各个试件的约束区长度和箍筋配箍特征值,将计算值与试验值进行比较,得出基于剪力墙顶点位移角限值的剪力墙截面变形能力设计方法相对较好,并指出了需要进一步研究的问题。
Based on the displacement ductility, the calculation method of the deformation capacity of the shear wall based on the displacement limit of the shear wall apex and the plastic corner is introduced. Using the test data of the existing shear wall specimens, the length of constraint area and the characteristic value of the stirrup ferrules in each specimen were calculated according to the above three methods respectively. Comparing the calculated values with the experimental values, The method to design the deformation capacity of the shear wall with the limit value of the vertex displacement is relatively good, and the problems that need further research are pointed out.
