本研究深入探讨了逆风地形从开放的国家过渡到郊区的复杂动力学及其对低层建筑的风压和风力的影响。进行了先进的风洞实验，重点是两个关键的距离参数：建筑物的接近迎风过渡补丁和补丁的长度。这种方法允许细致入微的检查的随机特性的风压，不同于标准的开放地形的情况下。此外，通过将我们的结果与传统的开放地形暴露进行比较，并与ASCE 7-16指定区域对齐，本研究为地形过渡对建筑设计的影响提供了新的见解。这些发现大大推进了我们对不同地形下风荷载估计的理解，为结构设计和风工程提供了有价值的观点。
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.
