摘要: 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。Abstract: In order to study the deformation capacity of steel reinforced concrete (SRC) shear walls,the relationship between drift ratio and cross sections curvature,edge strain,transverse reinforcement characteristic value are theoretically deduced according to SRC shear walls test with low-cycle reversed loading. A drift-based deformation capacity design method was proposed for SRC shear walls. The reliability of the method was verified through test results. It was obtained that the relationships about the drift ratio,the axial compression ratio,the transverse reinforcement characteristic value and shear span ratio. The allowable axial load ratios of SRC shear wall in different seismic grades and transverse reinforcement characteristic value were proposed.
