摘要(Abstract):

通过理论分析和数值计算,研究了设置约束边缘构件的矩形截面剪力墙轴压比限值。研究结果表明,影响混凝土剪力墙轴压比限值的主要因素为约束箍筋的配箍特征值、剪力墙的高宽比和顶点目标位移角值,据此提出了确定轴压比限值的方法,同时也给出了剪力墙截面变形能力的设计方法。通过10个剪力墙试件理论计算与试验目标位移角的对比分析,说明了该方法的可靠性。
Through theoretical analysis and numerical calculation,the allowable axial load ratio of rectangular section shear wall with confined boundary elements were studied.The results show that the transverse reinforcement characteristic value,the aspect ratio and the target top displacement ratio are the main factors influencing the allowable axial load ratio of the shear wall.A method of determining the allowable axial load ratio is proposed.The design method of sectional deformation capacity is also given.The comparison of calculation results and test results of ten shear wall specimens illustrates that this design method is feasible.
