| 摘 要： | 本文通过54根无腹筋、109根有腹筋钢筋砼连续梁及约束梁和17根仅配弯筋的约束梁的试验,研究了剪跨比m、高跨比1/h、弯矩比(?)、纵筋配筋率μ、配箍率μ(?)的变化规律和弯起钢筋A(?)对抗剪强度的影响,提出了对我国现行的《钢筋混凝土结构设计规范》(TJ 10-74)中的抗剪公式的修改建议,本文可供修订我国规范时参考。

| Abstract: | Based on shear tests of 54 R.C. continuous and restrained beams without web reinforcement,109 R.C. continuous and restrained beams with web reinforcement and 17 R.C. restrained beams with bent-up reinforcement only, the influence of shear strength in such beam with shear span ratio m, span depth ratio l/h0, moment ratio n and ratio of longitudinal reinforcement μ as well as the effect of bent-up reinforcement Asb on shear strength have been studied. In this paper, suggestions for shear strength formulae are put forward, which can be used as reference in revising the current design code ( TJ0-74) . |
