Summary In this paper, wind tunnel experiments on wind loading of a vaulted free roof with a side ratio of W/B = 1 were carried out. The effect of rise/span ratio f/B and wind direction on the characteristics of mean wind pressures and forces acting on the whole roof were investigated based on the results of the wind tunnel experiments. Then, according the distributions of the most critical maximum and minimum peak wind force coefficients on the roof irrespective of wind direction, the positive and negative peak wind force coefficients for designing the cladding/components of the roofs were proposed.
