摘要

摘要: 为探究钢-混凝土组合结构地铁车站的抗震性能，基于1995年在日本阪神地震中遭受严重破坏的大开车站，首先基于ABAQUS软件对钢筋混凝土结构地铁车站在阪神地震中的震害反应进行模拟分析，与大开车站的实际破坏现象进行对比，验证有限元建模技术可靠；在其他参数不变情况下，将大开车站的中柱、顶板以及梁替换为钢-混凝土组合构件，建立两种不同的组合结构地铁车站有限元模型，基于侧墙层间位移角、中柱水平位移时程曲线等指标与大开车站的震害模拟结果进行对比，分析不同结构形式下地铁车站的抗震性能差异。结果表明：仅采用钢管混凝土中柱的地铁车站结构抗震性能最好，其中柱水平位移比另两种结构约小21%；在加速度峰值时刻，其侧墙层间位移角比钢-混凝土组合结构约小25%~28%，比大开车站结构约小12%~13%。

Abstract: In order to investigate the seismic performance of the steel-concrete composite structure subway station, based on Daikai Station, which was seriously damaged in the Hanshin earthquake in 1995, the seismic damage response of the reinforced concrete subway station in the Hanshin earthquake was first simulated and analyzed by using the ABAQUS software, and then compared with the actual damage phenomenon of Daikai Station to verify the accuracy and reliability of the finite element model. Under the assumption that all other parameters remained constant, Daikai Station's central column, roof, and beam were substituted with steel-concrete composite members, and two distinct composite structure subway station finite element models were established. The inter-storey drift angle of the side wall and the horizontal displacement time-history curve of the central column and other indicators were compared with the seismic damage simulation findings of Daikai Station, and the seismic performance difference of the subway station under different structural forms was investigated. The results showed that the subway station construction with solely concrete-filled steel tubular columns had the best seismic performance, with the horizontal displacement of the central column being around 21% less than the other two structures; at the peak acceleration moment, the inter-story displacement angle of the side wall was about 25% to 28% smaller than that of the steel-concrete composite structure and approximately 12% to 13% smaller than that of Daikai Station's structure.
