Side sway deflections in the members caused by wind or seismic forces are often ignored by structural engineers but must be considered, especially when the cladding on the top of the canopy is glass. If wind loading analysis is not done correctly the resulting effects could include collapsed windows and doors, ripped off roofing, and more. Canopies can either be free-standing structures or can be attached as a structural component to a main building structure. The formula in determining the design wind pressure are: For enclosed and partially enclosed buildings: \(p = qG{C}_{p} -{q}_{i}({GC}_{pi})\) (1), \(p = q{G}_{f}{C}_{p} -{q}({GC}_{pi})\) (2). 01/26/2023 How to calculate the wind pressure on the main structure of a canopy roof ? Figure 8. Wind direction Windward +ve . The Foreword to the Singapore National Annex to EN 1991-1-4 Wind Actions has a minimum horizontal load requirement (1.5% characteristic dead weight). For example, the American Society of Civil Engineers ASCE 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, does not differentiate between the different types of canopies and recommends that canopies be designed as Components and Cladding structures for wind loads. 9 Determine wind force Fw acting on structure through vectorial summation of: However, for high-rise buildings, the parent wall of the building is much taller than for short buildings, which increases the downward force acting on the canopy, as shown in Figure 1.
