Chongqing Raffles City

Complex wind engineering for a unique cluster of towers linked by a skybridge

Chongqing Raffles City is an 8.8 million sq. ft. mixed-use development comprising eight tall towers integrated into an urban hub that includes a metro station and a ferry terminal. Because the design was so complex, we determined that we’d have to undertake multiple types of wind tunnel tests to gain a robust understanding of the loads the structure would experience. The results of our study – and the resulting design guidance – helped to optimize the structural design of this landmark project. We believe the approach will serve as an important benchmark for structural wind load studies for tall buildings with skybridge links.
