Renovation structural design of Shanghai Hongqiao International Airport Terminal 1
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.
