Description

In multi-tower and/or multi-phase developments, the impact of prominent nearby surroundings can play a large role in the aerodynamic conditions of proposed developments. This paper focuses on two case studies: i) two 160 m tall residential towers atop a prominent transportation terminal and ii) a tall (220 m) residential tower in complex terrain with significant future development. Comparisons will be made of the structural wind loads on the towers under various sheltering conditions. Both cases quantifies the amplification of wind loads due to vortex shedding off an existing upwind building 4 to 6 building widths upstream, as well as the role that a future development might play in modifying these amplifications. Comparisons will also be made to various empirical methods. This study also examines the aerodynamic impact of the two respective proposed towers in case i) as a result of their relative proximity within 2 building widths.
