Computation of Wind Pressures on L‐Shaped Buildings
Publication: Journal of Engineering Mechanics
Volume 119, Issue 8
Abstract
The paper presents the numerical prediction of turbulent wind pressures on the surfaces of L‐shaped buildings (either in plan view or in cross section) for different wind directions. The computer program developed for this purpose solves the time‐averaged Navier‐Stokes equations by using the turbulence model for closure. A zonal treatment methodology has been applied for the formulation of boundary conditions of turbulence properties ( and ). The computational procedure is applicable to any arbitrarily shaped building composed of two rectangular blocks and wind blowing from any direction. A nonuniform grid‐generation routine applicable to these building configurations was developed. Naturally, only mean values of wind‐induced pressures on the building envelope can be evaluated by the present numerical approach. Computed pressures have been compared with experimentally obtained values for a stepped‐roof building (L‐shaped in cross section). Good agreement is found for normal wind directions, and differences exist in oblique wind cases.
