ABSTRACT
Abstract The assessment of wind loading on building roofs requires good knowledge of the interaction between meteorological, aerodynamic and structural aspects of the problem. The paper presents some useful experimental results obtained from wind tunnel tests performed in the Wind Engineering Laboratory (WEL) at the Technical University of lasi concerning the particular values of the pressure coefficients on pitched roofs with complex geometric shapes utilised in the third climatic zone. The experimental programme has been carried out in the WEL to evaluate how various factors influence the wind action on pitched roofs. Experimental measurements have been performed to determine the effects of the following factors:
• general slope and local change in slope, • wind direction with respect to the building main axes, • coupling of two or more sections in different configurations, • local pressure distribution at ridges eaves and overhangs, • geometrical discontinuities due to special architectural features, • Height regime of the surrounding buildings, etc.
