In designing a weather-tight joint, it is important to understand all of the forces acting upon it. One significant force is the wind pressure. The paper describes the pressure distribution on a high-rise building and how it can be determined. The variation in pressure with height is considered, as well as the effect of corners. It also examines the role of the wall design in the determination of pressure loads. Results from wind tunnel tests of two rainscreen wall systems are presented. The results show the effects of lateral flow within the airspace behind the rainscreen on the mean and fluctuating pressures across the rainscreen and across the inner wall.
