AbstractThe authors determined the pressure differences caused by wind action across the walls of a 44-storey building and a 34-storey building in the centre of a large city. They did a regression analysis of the pressure records to determine the wind pressure coefficients for the two buildings. The coefficients varied considerably with variations in direction of the vertical wind velocity gradient and the shielding effect of adjacent buildings. The on-site wind speeds recorded were compared with wind velocities measured at the meteorological station. It was found that the relationship between the two observations varied with the general configuration characteristics of the terrain at the two locations.
