[提要]  進(jìn)行了11根鋼筋混凝土深受彎構(gòu)件在集中和均布荷載作用下受剪性能的試驗(yàn)研究，結(jié)合以往的研究成果，較詳細(xì)地分析了混凝土深受彎構(gòu)件的剪跨比、跨高比、縱筋配筋率、豎向和水平腹筋等對(duì)其受剪承載力的影響。提出了鋼筋混凝土深受彎構(gòu)件受剪承載力計(jì)算的建議公式，供我國(guó)混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范修訂時(shí)補(bǔ)充這方面內(nèi)容參考。

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
