本文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”计算约束混凝土墩柱截面的弯矩—曲率关系 ,从而得出约束混凝土墩柱的截面曲率延性系数同轴压比、弯矩、箍筋的关系 ,为钢筋混凝土墩柱的延性抗震设计提供依据
In this paper, using the “strip method” to calculate the moment-curvature relationship of the cross-section of the confined concrete pier by using the stress-strain curve of the reinforced concrete and the confined concrete, the coercive force of the confined concrete pier is obtained. Moment and stirrups. It provides the basis for the ductile seismic design of reinforced concrete piers
