Mean Wind Pressure Distribution on Low-Rise Buildings with Canopies

Abstract eng:
It is a general practice to provide a flat or sloping slab called canopy at the entrance door of the building at the ground level wherever space permits. This may be cantilever type slab or supported one. While designing various structural elements and cladding units of buildings for wind loads, values of wind pressure coefficients are obtained from relevant code of practice where in the values are available for buildings with plane cladding only. Very limited information is available regarding wind pressure on canopies in codes of practice on wind loads including Indian Standard Code of Practice. Present paper describes the results of the wind tunnel study carried out on models of gable roof buildings with canopies. Wind pressure coefficients are calculated from the measured values of mean pressures on wall and roof surfaces and compared with those for building without canopy in order to observe the influence of canopy on wind pressure distribution.
