The effect of open-to-suburban terrain transition on wind pressures on a low-rise building

This study delves into the complex dynamics of upwind terrain transition from open country to suburban areas and its effects on wind pressures and forces on low-rise buildings. Advanced wind tunnel experiments were conducted, focusing on two critical distance parameters: the building's proximity to the upwind transition patch and the patch's length. This approach allowed for a nuanced examination of the stochastic characteristics of wind pressures, differing from standard open terrain scenarios. In addition, by comparing our results with conventional open terrain exposures and aligning with ASCE 7-16 designated zones, this research offers novel insights into the terrain transition impact on building design. These findings significantly advance our understanding of wind load estimations in varied terrains, contributing valuable perspectives to structural design and wind engineering.
