均布荷载作用下混凝土深梁抗剪性能

Research on Shear Behavior of Reinforced Concrete Deep Beam under Uniform Load

以混凝土深梁作为研究对象,通过有限元软件Ansys模拟其在均布荷载作用下,箍筋配筋率和截面有效高度2个因素对梁抗剪性能的影响。结果表明:随着箍筋配筋率的增大,深梁产生的跨中位移不断减小,随着截面尺寸的增大,深梁产生的切应变不断减小,说明箍筋配筋率和截面有效高度的增大有利于对提高梁的抗剪性能。

Taking the concrete deep beams as research object,the impact of the two factors of stirrup reinforcement ratio and section effective height on beam shear performance was simulated though the finite element software of Ansys under the action of uniformly distributed load.The results shows:with the increase of stirrup reinforcement ratio,the displacement which was generated by deep beam shear strain decreases continuously.With the increase of section size,shearing strain which was produced by deep decreases continuously.It illustrates that effective height increases stirrup reinforcement ratio and section is beneficial to increase the shear properties of the beam.
