本文研究剪扭作用下的钢筋混凝土构件的性能,并根据实验所得到的斜弯破坏模式,采用逐步递增混凝土表面应变的非线性分析方法,对扭剪比(Mt/Qb)大于0.5的扭型破坏的构件的内力与变形作了全过程分析,最后将实验结果与理论计算作了比较。 This paper studies the performance of reinforced concrete members subjected to shearing and torsion, and according to the oblique bending failure mode obtained by the experiment, adopts a non-linear analysis method that gradually increases the surface strain of concrete, and the torsional shear ratio (Mt/Qb) is greater than 0.5. The internal forces and deformations of the destroyed components were analyzed in the whole process. Finally, the experimental results were compared with the theoretical calculations.
