摘要
钢筋混凝土受扭构件最小配筋率是为防止构件受扭一开裂就出现突然脆性破坏所需的最低配筋率 ,目前国内外对此尚无较为深入的研究。在试验研究分析的基础上 ,并参考国外规范的有关规定 ,对钢筋混凝土受纯扭及受弯剪扭构件的箍筋和纵向钢筋的最小配筋率 ,提出了便于设计应用的计算公式 ,为修订《混凝土结构设计规范》(GB5 0 0 1 0 )的有关条文 。
There are no thorough research on the minimum steel ratio of reinforced concrete member under torsion at home and abroad.Based on experimental research and foreign codes,formulas of the minimum ratio of longitudinal steel and stirrups in member under pure torsion or torsion,shear and bending are obtained,which are easy to apply in design.It presents the reliable basis for revising the relative regulations in Code for Design of Concrete Structure (GB50010—2002).
