摘　　要：对２２根无腹筋双向受弯混凝土矩形截面梁进行了科截面抗剪的试验研究，探讨了其抗剪性能，着重分析了影响抗剪强度的５个主要因素：纵筋配筋率、混凝土强度、剪跨比、荷载斜弯角、截面高宽比，为探讨抗剪强度理论计算方法提供了试验依据．Twenty-two concrete rectangular beams without web reinforcement under biaxial bending were tested to explore the shear behavior. The five main factors affecting the shear strength were analyzed: longitudinal reinforcement ratio, concrete strength, the shear span-depth ratio, load inclination, the depth-width ratio of the cross section, thereby providing the test basis for theoretical computation of the shear strength.
