为研究近海环境下耐久性损伤对高速铁路桥梁地震易损性的影响,通过建立高速铁路多跨刚构桥OpenSEES非线性有限元模型,考虑近海环境下高速铁路桥梁服役年限内钢筋锈蚀及其与混凝土黏结滑移性能退化,基于IDA方法进行非线性时程分析,确定桥梁各构件损伤指标并建立其时变地震易损性曲线;基于二阶界限法,考虑各构件相关性,进行高速铁路桥梁系统时变地震易损性分析。结果表明:全寿命周期内,近海高速铁路桥梁系统时变地震易损性随服役年限延长而增大,轻微损伤的超越概率随服役时间变化明显;随着损伤加剧,各状态的超越概率随服役时间延长变化减小;以服役100年为例,高速铁路桥梁系统在8度罕遇地震作用下发生轻微损伤、中等损伤、严重损伤及完全破坏的超越概率分别为97.5%、91.6%、21.5%、1.4%,分别比新建时增大了5.3%、15.1%、11.1%、1%。
To study the impact of durability damage on the seismic fragility of high-speed railway bridges in offshore environments, this paper builds a nonlinear finite element model of high-speed railway multi-span continuous rigid frame bridges based on the OpenSEES finite element platform, considering the corrosion and bond slippage of steel bars within the service life of high-speed railway bridges in offshore environments. The IDA method is used for nonlinear time-history analysis to determine the damage index and the seismic fragility curve of each component of the bridge. Based on the second-order limit method, and considering the relevance of each component, the time-varying seismic fragility analysis of the high-speed railway bridge system is carried out. Studies show that the time-varying seismic fragility of offshore high-speed railway bridge systems increases with the extension of service life in the full life cycle, and the exceedance probability of minor damage changes significantly with the time of service; as the damage intensifies, the exceedance probability of each state decreases with the extension of service time; taking 100 years of service as an example, the exceedance probability of minor damage, moderate damage, severe damage and complete failure of the bridge system under the action of a rare earthquake of intensity 8 is 97.5%, 91.6 %, 21.5%, and 1.4%, respectively, increasing by 5.3%, 15.1%, 11.1%, and 1% respectively compared with the newly built bridge system.
