Wind loads on free-standing canopy roofs have been studied experimentally. Three types of roof geometries, i.e. gable, troughed and mono-sloped roofs were tested. Wind pressures were measured simultaneously at many points both on the top and bottom surfaces of the roof model for various wind directions. Based on the results for the most critical positive and negative peak pressure coefficients irrespective of wind direction, the wind force coefficients for the design of cladding and its immediately supporting structures are proposed. Correlation between the wind force and moment coefficients is investigated, and appropriate wind force coefficients for the design of main wind force resisting systems are proposed. Axial forces in the columns supporting the roof are regarded as the most important load effect. Two loading patterns causing maximum tension and compression of columns are considered.
