[提要]  进行了11根钢筋混凝土深受弯构件在集中和均布荷载作用下受剪性能的试验研究，结合以往的研究成果，较详细地分析了混凝土深受弯构件的剪跨比、跨高比、纵筋配筋率、竖向和水平腹筋等对其受剪承载力的影响。提出了钢筋混凝土深受弯构件受剪承载力计算的建议公式，供我国混凝土结构设计规范修订时补充这方面内容参考。

An experimental research of 11 R C deep fiexural members in shear under concentrated load and unifonlly distributed load is achieved. The main factors affecting the shear capacity of R C deep flexural members such as shear-span ratio, span-depth ratio, longitudinal steelIatio and web reinforcement are discussed in detail. The design for-mulaes for shear capacity of R Cdeep flexural members are proposed,and this may be a reference for revision of China design code.
Keywords: deep flexural members; deep beams; short beams; shallow beams; shear capacity
