为研究型钢混凝土(SRC)剪力墙的变形能力,在已有的弯曲破坏的SRC剪力墙拟静力试验的基础上,通过理论分析,推导出SRC剪力墙极限位移角、截面曲率、边缘应变和配箍特征值之间的关系,提出基于极限位移角的SRC剪力墙变形能力设计方法。通过与试验结果进行对比,说明该方法的可靠性。以此为基础,研究轴压比、剪跨比、配箍特征值等因素与SRC剪力墙极限位移角的关系,并提出不同抗震等级、不同配箍特征值下轴压比的限值。
In order to study the deformation capacity of SRC shear wall, based on the existing pseudo-static test of SRC shear wall with curved failure, the ultimate displacement angle, section curvature, Edge strain and the characteristic value of the hoop, the design method of SRC shear wall deformation capacity based on the limit displacement angle is proposed. By comparing with the test results, the reliability of the method is demonstrated. Based on this, the relationship between the axial displacement ratio, shear span ratio and the characteristic value of the hoop and the ultimate displacement angle of the SRC shear wall are studied. The limits of the axial compression ratio under different seismic levels and different characteristics of the hoop are proposed.
