Wind tunnel study of interference effects between twin super-tall buildings with aerodynamic modifications
Abstract Wind tunnel experiments were carried out to investigate the interference effects between twin super-tall buildings with aerodynamic modifications. The contour plots of interference factors are presented to quantitatively assess the interference effects on global aerodynamic loads, wind-induced response and local surface pressure coefficients. The results show that the dynamic wind loads and responses are greatly increased in critical tandem and staggered arrangements of the twin towers and the minimum peak negative pressure coefficients are approximately 30% larger than those without interference. This study provides useful results for identifying the potential problematic arrangements of twin super-tall buildings and to further the understanding of the underlying mechanisms of the aerodynamic interference.
