Abstract
Six pressure models of high rise buildings were tested in a boundary layer wind tunnel. Five had triangular cross sections with configurations of Straight Triangle, Corner cut, 60° Helical, 180° Helical and 360° Helical, and the other had a configuration of Clover. This study investigates variations in along-wind and crosswind overturning moment coefficients, power spectral densities, and trajectories of various wind force coefficients, as well as the effects of helical angle and aerodynamic modifications on wind forces and peak spectral values. The results show that the helical models had more effect on aerodynamic characteristics.
