[摘要]  苏州汽车北站改建工程，主体建筑为站务楼，重点设防类建筑。左塔下方为入口门厅，二~三层均在楼面上开大洞27×24m，此范围的楼板有效宽度几乎为0。为提高大洞周边柱的抗震性能，大洞周边柱采用钢管混凝土柱，其上部设转换钢结构屋盖，很好解决了建筑上大跨度、大空间的需要。设计时采取了基于性能的抗震设计和比现行规范要求更为严格的抗震措施。经对结构进行多模型的弹性分析和时程分析，其工作状态和性能均能达到预期性能目标和规范要求。

Abstract：North Coach Station Reconstruction Project in Suzhou,which main part is a station building. There is a big hole in the second and third floor in the left unit. Concrete filled steel tube columns are set around the big hole.Over the concrete filled steel tube columns is a transfer steel structural roof. The characteristics and structural design were introduced. A performance-based seismic design was adopted. The structure was analyzed with multi-model and several softwares. The results show that the work state and performance of the structure can meet the design goals of performance and criterion requirements.
Keywords: multistory structure; earthquake resistance objectives; skip-floor concrete filled steel tube columns; transfer steel structural roof
