This study was made during the first author's appointment at the Department of Building, Civil and Environmental Engineering, Concordia University, Montreal, Quebec, Canada, as visiting professor, supported by the Ministry of Education, Culture, Sports, Science and Technology, Japan, during the period from May 2002 to February 2003. The authors are much indebted to Mr. Kai Wang, graduate student of Concordia University, for his assistance with the experiments.

N2 - 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.
