摘要
讨论了钢筋混凝土无腹筋梁斜截面抗剪的影响因素 ,对比了中美规范抗剪承载力的计算公式以及抗剪最小配筋率的有关规定 ,指出 :中国规范在低强度的条件下与美国规范计算结果相当 ,但在高强度的条件下 。
The factors which affect the shear force resistance of non web reinforced (NWR) concrete beam were discussed. The calculating formulas of shear force resistance and minimum steel ratio of NWR beam respectively according to Chinese and American Codes were illustrated.The calculating results under different ranks of concrete strenghth were compared. The comparisons indicated that Chiese Code has lower shear force resistance reliability than American Code does under higher concrete strengh.
