弯、剪、扭共同作用下钢筋砼构件的强度

Strength of Reinforced Concrete Member under Combined Action of Bending, Shear and Torsion

本文采用变角空间桁架理论给出了钢筋砼构件弯-剪-扭强度相关方程,总结了国内近年来的主要试验成果,对这类构件强度的计算方法作了较深入的讨论。

By means of the theory of space-truss model with changeable angles, the constitutive equations of reinforced concrete members under the combined action of bending, shear and torsion in consie-ration of the interrelationship of their strength are presented. The main results of the tests performed in recent years have been summarized and the methods for evaluating the load-carrying capacities of this kind of members are discussed as well.
