客运专线桥梁基于性能的抗震设计研究
|
摘要
从基于性能的抗震设计理念出发,给出了客运专线桥梁结构的性能目标及各性能水准下的桥墩地震破损描述,明确并量化了桥墩各抗震性能目标的验算内容。给出了小震不坏及可控制中震损伤的验算方法,简化能力谱法计算位移延性系数,指出了大震时最大位移验算的不足,讨论了桥墩大震时地震损伤指数的计算与验算,通过算例详细介绍了基于性能的抗震设计方法与过程。
Performance objective and content of checking resistance verification for Passenger Delicated Railway bridge pier are embodied and quantified based on the theory of performance-based seismic design.The resistance verification is proposed,which can control the damage extent under the design earthquake and ensure safety of the pier under the low-level earthquake.The capacity spectrum method for calculating displacement ductility factor is proposed.The shortcoming of maximum displacement verification in current code is pointed out.The method for evaluating damage of RC bridge pier in high-level earthquake is given by using maximum displacement and hysteretic energy.The design procedure is demonstrated by using an example.
