均匀受力的混凝土深梁抗剪性能

Research on Shear Behavior of Reinforced Concrete Beam Under Uniform Load

主要通过有限元软件模拟研究混凝土深梁在均布荷载作用下,纵筋配筋率、混凝土强度等两个因素对其抗剪性能的影响。结果表明:随着纵筋配筋率的增大,深梁的产生切应力不断减小,随着混凝土的强度的增大,深梁的产生切应变不断减小,说明纵筋配筋率和混凝土强度的增大对提高梁的抗剪性能有利。

This paper mainly through the finite element software simulation research on reinforced concrete deep beams under uniform load,reinforcement ratio and concrete strength affect the performance of the shear. ＋ The results show that with the increase of the ratio of longitudinal reinforcement and depth, the generation of deep beam shear stress decreases continuously,with the increase of the strength of the concrete, the generation of deep beam shear strain decreases constantly, suggests that the increase of the longitudinal reinforcement reinforcement ratio and concrete strength is good for increase the shear properties of the beam.
