本文给出40根深梁构件实验结果。研究深梁在对称集中荷载下的工作性能,破坏形态和强度计算。讨论剪跨比、混凝土强度、加荷垫板尺寸、腹筋配筋率和纵筋配筋率对深梁抗剪强度的影响。根据拉杆拱受力模型导出抗剪强度计算公式,并与国内外约194根深梁实验结果比较,符合程度良好。对斜截面抗弯强度及深梁抗裂度问题亦进行讨论,并给出计算公式。

The experimental results of 40 deep beam members are given in this paper.The working performance, failure mode and strength calculation of deep beam under symmetric concentrated load are studied.The effects of shear span ratio, concrete strength, loading plate size, ratio of abdominal reinforcement and ratio of longitudinal reinforcement on the shear strength of deep beams are discussed.The formula for calculating the shear strength is derived from the tensile model of the draw-bar arch, and is in good agreement with the experimental results of about 194 deep beams at home and abroad.The problems of bending strength of inclined section and cracking strength of deep beam are also discussed, and the calculation formulas are given.
