摘要 自复位混凝土桥墩(SCCP)能够在抵御强震后有效控制残余变形,是一种具备优良抗震性能的新型桥墩体系。该文针对新型自复位混凝土桥墩,提出一种自复位混凝土桥墩损伤演化过程的简化分析模型,系统地描述了循环加载过程中滞回曲线的各个主要环节。在损伤演化分析中,通过引入3个损伤因子γu、γc和γr,阐明循环增大的侧向位移可能导致的3种损伤来源。通过与既有的试验数据的对比分析,验证了该文提出的简化分析模型的准确性和有效性。

Abstract:Self-centering concrete bridge piers (SCCP), which have been used to retrofit bridge piers to give better seismic response, effectively reduce residual displacements during severe earthquakes. This study gives a simplified theoretical model for self-centering concrete bridge piers including a stiffness deterioration analysis and lateral force-displacement analysis. The stiffness deterioration analysis introduces 3 damage factors for γu, γc and γr. These damage factors illustrate the damage caused by increasing lateral displacements. The theoretical model has been validated against existing experimental data with good agreement.
