摘要
上海虹桥国际机场T1航站楼历经多次改造和扩建,介绍了2018年实施完成改造设计的难点和特点。针对不同年代建造的结构单体共存问题,通过全面比较选择拆除或保留原结构,合理确定不同单体的后续工作年限。A楼出发大厅屋盖拆除新建,为减小改造对原结构的影响,采用钢屋盖-立面-雨篷一体化的结构方案;介绍了一体化结构的概念方案、分析结果和优化设计过程。1988年设计的B楼原结构抗震构造薄弱、抗震性能差,采用减少变形缝、改变结构体系、增设屈曲约束支撑等手段提升其抗震性能,满足大震不倒的设防要求。
Terminal 1 of Shanghai Hongqiao International Airport has undergone multiple renovations and expansions,the difficulties and characteristics of the renovation design completed in 2018 were introduced.Based on the coexistence of structural units built in different eras,a comprehensive comparison was made to choose between demolishing or retaining the original structure,and the subsequent working years of different units were reasonably determined.The roof of the departure hall on Building A was demolished and rebuilt.In order to reduce the impact of the renovation on the original structure,an integrated structural scheme of steel roof-facade-canopy was adopted.The concept scheme,analysis results and optimization design process of the integrated structure were introduced.The original structure of Building B designed in 1988 had weak seismic resistance and poor seismic performance.Measures such as reducing deformation joints,changing the structural system,and adding buckling restrained braces were adopted to improve its seismic performance and meet the fortification requirements of being able to withstand rare earthquakes without collapsing.
