双向受弯梁受剪承载力计算方法探析

On Calculation Method of Shear Capacity of Reinforced Concrete Beams under Biaxial Bending

在工程实践中,对双向受弯梁的斜截面受剪承载力计算通常是简化成按两个方向单向受弯梁分别计算。本文以32根集中荷载作用下混凝土双向受弯梁斜截面受剪性能试验为依据,对该方法的适用性进行探讨。研究结果表明这种简化设计方法是不安全的。

In engineering practice, calculation of shear capacity of biaxial bending diagonal plane is usually simplified into two by the direction for gaining each shear capacity of diagonal plane. In this paper, the applicability of the method is discussed with regard to the function experiment of shearing concrete beams under biaxial bending diagonal plane with 32 concentrated loads. The result shows that this simplified design is not safe.
