Adverse Wind Loads on Low Buildings Due to Buffeting
Publication: Journal of Structural Engineering
Volume 110, Issue 10
Abstract
The effect of large nearby buildings on the wind loading of low buildings has not been examined in the past. Wind loads for low buildings specified by current standards and Codes of Practice originate from wind tunnel studies on isolated buildings and give no guide for the assessment of loads under conditions of buffeting. The current paper presents the results of an experimental study carried out in a boundary layer wind tunnel in order to determine the wind loads on low buildings of different geometries (eave height and roof slope) in the presence of a tall nearby building at various relative locations. Results show significant adverse effects (wind load amplifications higher than 200%) for particular building proximity configurations. The complexity of the problem, however, indicates that it is very difficult to treat these buffeting effects with any degree of generality. Alternatively, it is suggested that local building officials should require the use of higher design loads after seeking a specialist's advice and possibly performing special wind tunnel tests.
