摘要:
以某两层三跨地铁车站为案例，建立了土结构的二维有限元模型。根据地铁车站结构的动力响应特性，选取了基岩处和地铁车站结构底部的加速度峰值、速度峰值、位移峰值、Arias强度为地震动强度指标，并以结构最大层间位移角作为结构性能指标，采用增量动力分析，建立了不同地震动强度指标与结构性能指标的关系曲线，并对该地铁车站抗震性能评估的有效性进行分析。
Abstracts:
Taking the case of certain two-storey-three-span metro station, a soil-structure 2D finite element model is established. According to the dynamic response characteristics of metro station structure, the peak acceleration, peak velocity, peak displacement, and Arias intensity at both the bedrock and metro station structure bottom are selected as ground motion intensity measure. By adopting incremental dynamic analysis, the relationship curve of different ground motion intensity measure and structure performance measure is established. Effectiveness of metro station seismic performance evaluation is analyzed.
