摘　　要：在13根集中荷载作用下钢筋砼双向受弯约束梁斜截面抗剪试验研究的基础上,采用等效梭形截面法,将双向受弯约束梁转化为单向受弯约束梁,并推出集中荷载作用下钢筋混凝土双向受弯约束梁斜截面抗剪强度的计算方法.Based on the test results of thirteen restrained R.C. members with web reinforcement subject to biaxial concentrated load,the method of equal effective shuttle-shape section was adopted,the restrained beams under biaxial bending is turning into the restrained beams under axial bending.The formula for calculating the shear strength of restrained reinforced concrete members under biaxial bending subject to biaxial concentrated load is presented in this paper.

关 键 词：集中荷载 双向受弯 约束梁 等效梭形截面法 抗剪强度
