中文摘要：
“房桥合一”新型高铁客站的站厅层往往以大跨度钢桁架为其主要结构特征。基于此，以天津西站典型站厅结构为例，提取其主要结构单元，选取多条竖向地震强震记录，并综合采用静力和动力弹塑性方法，研究典型站厅结构大跨度钢桁架单元的竖向地震屈服机制和破坏特征。此外，与站厅结构动力弹塑性计算结果对比，进一步验证了多模态Pushdown方法在大跨结构竖向抗震性能评估中快速有效。
英文摘要：
The station hall of new type of integrated building - bridge high - speed railway station usually posses- ses long - span steel trusses as its main structural feature. Considering this point, the station hall of Tianjin West Railway Station was referred and adopted to extract the main structural unit, select multiple vertical strong earth- quake records, adopt taken as an example elastic -plastic methods synthetically. Then, the failure characteristic and yielding mechanism of typical station hall structure under vertical earthquake excitation were systematically studied. In addition, by comparing with dynamic elastic - plastic calculating results of station hall, the advanta- ges of multiple modal Pushdown method in seismic performance assessment of long - span structure were further validated.
