Interference effects of two and three super-tall buildings under wind action

Most previous investigations on interference effects of tall buildings under wind actions focused on the wind induced interference effects between two buildings, and the interference effects of three or more buildings have seldom been studied so far due to the huge workload involved in experiments and data processing. In this paper, mean and dynamic force/response interference effects and peak wind pressure interference effects of two and three tall buildings, especially the three-building configuration, are investigated through a series of wind tunnel tests on typical tall building models using high frequency force balance technique and wind pressure measurements. Furthermore, the present paper focuses on the effects of parameters, including breadth ratio and height ratio of the buildings and terrain category, on the interference factors and derives relevant regression results for the interference factors.
