Wind loads on free-standing canopy roofs

Part1 Wind force coefficients for the design of cladding and its immediately supporting structures

Abstract

Wind force coefficients for the design of cladding and its immediately supporting structures of free-standing canopy roofs are proposed based on the distributions of the most critical positive and negative peak wind force coefficients regardless of wind direction. The roof area is divided into several zones and peak net pressure coefficients, both positive and negative, are given to each zone. The proposed values are compared with the results of previous studies as well as with the provisions of the AS/NZ and Japanese Standards. It is found that the Japanese Standard overestimates the design wind loads.
