摘　　要：对 13根集中荷载作用下钢筋砼矩形截面有腹筋双向受弯约束梁进行了斜截面抗剪试验研究 探讨了其抗剪机理和抗剪性能 ,分析了 4个影响抗剪承载力的主要因素 :荷载斜弯角、配箍率、剪跨比及弯矩比 。Thirteen reinforced concrete rectangular restrained beams with web reinforcement subjected to biaxial concentrated load were tested to explore the shear mechanism and the shear behavior.Four main factors affecting the shear strength were analyzed:the inclination of load,the stirrup ratio,the ratio of span length and the ratio between the negative and positive moment.Thereby the theoretical and test basis of the shear strength is provided.

关 键 词：双向受弯 约束梁 抗剪承载力 有腹筋 集中荷载
