由于频繁的故障和损失，低层住宅建筑对飓风等极端风事件的脆弱性日益受到关注。建造高架低层建筑物是为了减少飓风期间浪涌和洪水造成的水动力负荷。然而，由于目前缺乏信息，风荷载对高架海岸结构是没有充分解决目前的国际准则。为了解决这一知识差距，进行了大规模的实验研究，以精确地确定风对不同层数和不同高跷高度的高架房屋的影响。在这项研究中，比较各种测试配置，以显示对所产生的风荷载的影响，提高住宅。特别是，这项工作调查的峰值压力系数和风力的建筑屋顶，墙壁，地板底面。实验程序通过使用计算流体动力学（CFD）的数值模拟进行补充，以评估模型周围的气流以及地板下的气隙对改变空气动力学的作用。局部峰值压力模式和结构设计的风荷载进行了分析，以期发展的建筑规范规定。将外部地板表面的推荐外部压力系数与低层建筑的平屋顶表面的推荐外部压力系数进行比较。
The vulnerability of low-rise residential buildings to extreme wind events, such as hurricanes, is an escalating concern due to the frequent failures and losses. Elevated low-rise structures are constructed to reduce the hydrodynamic load from surges and flooding during hurricanes. However, due to the current lack of information, wind loading on elevated coastal structures is not adequately addressed in current international guidelines. To address this knowledge gap, large-scale experimental studies were conducted to precisely determine wind effects on elevated houses with different numbers of stories and varying stilt heights. In this study, comparisons are presented on various tested configurations to show the effect of elevating residential houses on the resulting wind loads. In particular, this work investigates the peak pressure coefficients and wind forces on the building roof, walls, and floor underside. The experimental program was supplemented by numerical simulations using Computational Fluid Dynamics (CFD) to assess the airflow around the model and the role of the air gap underneath the floor on altering the aerodynamics. Local peak pressure patterns and wind loads for structural design were analyzed with a view to the development of building code provisions. The recommended external pressure coefficients for the exterior floor surface are compared to those for a flat roof surface of a low-rise building.
