摘要:
为利用截面设计参数定量计算钢管混凝土组合桥墩抗震延性,选择矩形桥墩作为研究对象,鉴于我国桥墩服役期工作轴压比一般处在0.1~0.4的现状,选择此区间作为研究范围,根据平截面假定、力的平衡和材料本构关系,分别建立了截面屈服曲率和极限曲率关于截面设计参数的解析公式,并通过数值方法验证了解析公式的正确性。将截面极限曲率与屈服曲率之比即曲率延性系数作为评价指标,最终建立评价指标关于截面设计参数的解析公式。研究结果表明:利用推导的解析公式可以实现对钢管混凝土组合桥墩曲率延性系数的定量计算,结果可信;通过曲率延性系数的比较,证明在耗材相同的情况下,钢管混凝土组合桥墩比箍筋约束混凝土桥墩具有更好的抗震延性。
