WIND LOADS ON FREE-STANDING CANOPY ROOFS: A REVIEW

Yasushi Uematsu, T. Stathopoulos

Open full text 11 citations

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 results. The comparisons are restricted to the clear flow case with no obstructions under the roof. A discussion is made of the subjects to be investigated for making the provisions more appropriate.
