配筋砌体剪力墙约束边缘构件的研究

摘要

A study on determining proper details of the confined boundary member(CBM) of the reinforcedblock-masonry shear wall(RSW) is presented.Through the discussion on curvature ductility enhancement,favorable fortification details,including the reinforced mechanical ratio and the boundary member length of CBM,are suggested for the confinde concrete boudary member and the comfined masonry boundary member.A variable andalysis is then conducted to investigate the variables'effects on the curvature ductility of RSWs strengthened wyith the suggested CBMs.Ductility formulas are put forward for RSWs with the suggested details,among which are formulas of the curvature ductility which grees well with the numercal results.%通过对配筋砌体剪力墙约束边缘构件的研究,提出相应的构造措施.通过设置了约束边缘构件后,墙体延性的变化,分析确定了约束混凝土和约束砌体边缘构件的具体构造做法,在该做法的基础上,进行参数分析,确定各个参数的影响作用,并建议了设置约束边缘构件墙体的曲率延性计算公式.大量的数值计算表明,该公式与数值计算结果吻合.
