Structural Design of Shanghai Tower for Seismic and Wind Loading – A Comparative Study

A comparative study was conducted for the structural design of Shanghai tower for seismic action and wind loading. The analysis parameters, design methodology and structural responses for both seismic action and wind loading were addressed and compared. The design parameters for the design for wind loading, such as the along wind parameters, across wind parameters, damping ratio under different wind loading levels and dynamic properties, were then discussed. The design methodology, reference return period, base reactions for seismic action and wind loading were finally compared for the Shanghai tower project. The design parameters of the structural design for seismic action and wind loading and the comparative study results can be the references of the structural design of other super tall buildings.
