摘要
采用刚度退化三线性模型对某大跨度连续刚构桥实体工程进行了弹塑性动力时程分析,确定了桥墩塑性铰对结构抗震性能的影响,算例分析结果可为同类桥梁工程的抗震设计提供指导。
The paper adopts the stiffness degradation three-line model to have the elastoplastic dynamic time-history analysis of some large-span continuous rigid bridge, identifies the influence of pier＇s plastic hinge on seismic performance, and provides the direction for the seismic design for similar bridge constructions bridge project.
