【摘要】 分析了洞口大小、位置及腹筋形式、配筋量对简支开洞深梁承受集中力时剪切性能的影响，按洞口形态将开洞深梁划分为整体计算及洞口上下分别计算再叠加两类，并提出了相应的剪切强度计算公式，计算值与试验结果吻合更多还原

【Abstract】 The sive,position of the hole,the reinforced form,and steel ratios are analysized,which affect shear behavior of the simply deep holed-beam resisting concentrated forces. According to the hole type,two calculating ways are obtained,that is ,intergrity calculation and the upper,lower hole calculation respectively;then summarization,and the corresponding calculation formula of shear strength is given,the calculation value complying basically with the test results. deep holed-beam, truss model, shear strength更多还原
