本研究的目的是研究基于各种设计参数的圆形空心钢筋混凝土桥墩的非弹性行为和延性能力。这些桥墩的极限强度和延性随侧向钢筋的数量和布置、柱截面内外径比、轴载比和纵向钢筋百分比的变化而变化。总共八个具有这些设计变量的实心和空心圆形钢筋混凝土桥墩在恒定轴向载荷和循环反向水平载荷下进行了测试。计算机程序RCAHEST（高级评估系统技术中的钢筋混凝土分析）用于预测圆形空心钢筋混凝土桥墩的非弹性行为。此外，采用改进的侧向限制效应模型并将其纳入RCAHEST的结构单元库中。所提出的非弹性行为和延展能力的数值方法......
The purpose of this study was to investigate the inelastic behaviour and ductility capacity of circular hollow reinforced concrete bridge piers based on various design parameters. The ultimate strength and ductility of these bridge piers varied with the amount and arrangement of lateral reinforcement, the ratio of the inside to outside diameter of the column sections, the axial load ratio and longitudinal steel percentage. A total of eight solid and hollow circular reinforced concrete bridge piers with these design variables was tested under a constant axial load and cyclically reversed horizontal load. A computer program, the RCAHEST (reinforced concrete analysis in higher evaluation system technology), was used to predict the inelastic behaviours of circular hollow reinforced concrete bridge piers. Also, the modified lateral confining effect model was adopted and incorporated into the structural element library for RCAHEST. The proposed numerical method for the inelastic behaviour and ductility capacity...
