【摘要】 利用钢筋以及约束混凝土的应力－应变关系曲线，采用“条带法”计算约束混凝土压弯构件截面的弯矩－曲率关系，从而得出约束混凝土构件的截面曲率延性系数同轴压比、弯矩、箍筋的关系，为钢筋混凝土结构的延性抗震设计提供依据．更多还原

【Abstract】 In this paper "stripe- method" is used to calculate the relation of the bound concrete member bent- curvature according to the steel bar and bound concrete stress-strain curves. Consequently, the variation of the bound concrete member cross- section curvature with the axis- pressure, bent, cross - bound steel bar is obtained. This conclusion can offer the sustainment to the structure ductility earthquake- resisting design.更多还原
