[摘要]  蘇州汽車北站改建工程，主體建筑為站務(wù)樓，重點(diǎn)設(shè)防類建筑。左塔下方為入口門廳，二~三層均在樓面上開大洞27×24m，此范圍的樓板有效寬度幾乎為0。為提高大洞周邊柱的抗震性能，大洞周邊柱采用鋼管混凝土柱，其上部設(shè)轉(zhuǎn)換鋼結(jié)構(gòu)屋蓋，很好解決了建筑上大跨度、大空間的需要。設(shè)計(jì)時(shí)采取了基于性能的抗震設(shè)計(jì)和比現(xiàn)行規(guī)范要求更為嚴(yán)格的抗震措施。經(jīng)對(duì)結(jié)構(gòu)進(jìn)行多模型的彈性分析和時(shí)程分析，其工作狀態(tài)和性能均能達(dá)到預(yù)期性能目標(biāo)和規(guī)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
