Abstract
Previous studies of wind loads on free-standing canopy roofs have been surveyed. Focus is on the data obtained from wind-tunnel measurements in simulated atmospheric boundary layers as well as from full-scale measurements. Comparisons are made between these studies for some aerodynamic characteristics, such as mean and peak wind force coefficients. The wind load provisions in the current Building Standard Law of Japan are also compared with the experimental data. Based on the results, new provisions of the design wind force coefficients are proposed both for the main wind force resisting systems and cladding/components. A discussion is made of the subjects to be investigated for making the provisions more appropriate.
