Wind induced pressures on a large low-sloped gable roof building with parapet
This paper experimentally investigates how parapets with varying heights can alter the flow pattern around a large aspect-ratio low-sloped gable roof building. We examine the benefits and challenges of existing methods and utilize an open-jet wind test section, to accurately simulate real-world atmospheric boundary layer conditions. A model of a low-rise building was fitted with solid parapets of varying heights and tested in a comparative study to understand their impact on roof pressures. The study compares the standard approach to the experimental results and suggests improvements to wind zones and pressure coefficients. The parapet of fourteen percent of the building height is the most efficient at reducing mean, peak, and area-averaged wind loads compared to other sizes. However, the standard provisions underestimate roof pressures for components and cladding design.
