摘要:
为了有效控制地铁“建桥合一”结构在不同抗震设防水准下的损伤状态，基于性能的抗震设计方法，以多层次和个性化两大结构抗震设计理念为出发点，研究结构的性能水平与设防水准之间的关系，进而提出“建桥合一”结构的5级抗震设防水准，设定5个结构性能等级，建立 5 个抗震设防等级与 3 个设防目标的矩阵图。选取某“建桥合一”地铁车站作为案例，模拟分析其抗震塑性发展规律，得出“建桥合一” 结构抗震的薄弱环节是底层墩柱和站厅层边跨纵梁，应重点分析框架柱的抗震性能的结论。
Abstracts:
In order to effectively control the structural damage of the integral station-bridge under different seismic fortification conditions，a performance-based seismic design method is adopted，which starts from the multiple-level and individualized seismic design concepts，the relationship between the structural performance level and the waterproofing standard are studied. Then，the seismic waterproof level of magnitude 5 is proposed， 5 structural performance levels，5 seismic defense degrees and the matrix diagram of 3 fortification targets are established. Based on a practical case of integral station-bridge structure，the development law of seismic plasticity is simulated and analyzed，the result shows that the bottom pier column and the side span longitudinal beam of station hall are the weakest points，therefore，the seismic behavior of frame columns should be mainly analyzed.
