某矮塔斜拉桥墩柱的抗震性能分析与评价
|
摘要
为研究矮塔斜拉桥在地震作用下的抗震性能,采用纤维塑性铰模型对其进行地震反应分析。研究评价了各墩柱的抗震能力,并对比分析了非弹性铰对桥梁产生的耗能作用,为桥梁的抗震设计提供依据。
In order to verify the seismic performances of the low-pylon cable-stayed bridge,the elastoplastic analysis is given to the bridge,while the most worst cross-sections are replaced by plastic elements which are modeled by fiber elements.The research on the seismic capacity of the piers and the energy consumption of non-elastic hinges has been done and it provides the basis for a seismic design of the bridge.
