| Abstract | ||
| This study compares pressure distributions on non-structural components (doors, windows, soffits, and fascia), due to hurricane winds from Wall of Wind (WoW) facility tests, field measurements on a residential house in Satellite Beach, Florida, during Hurricane Nicole (2022), and computational fluid dynamics (CFD) simulations. WoW testing was on a full-scale single-story building, equipped with wireless pressure sensors and Scanivalve patches. Wind loads were measured in the field using the same sensor system. The CFD simulations reproduced wind tunnel flow conditions. Measured pressure coefficients (𝐶𝑝) on the doors and windows (with and without shutters), soffits, and fascia are compared against 𝐶𝑝 values under ASCE 7-22 provisions. Results indicate that the 𝐶𝑝 from field measurements is localized and strongly dependent on wind direction in urban surroundings. Aluminium storm shutters reduce positive 𝐶𝑝 values on doors and windows at some angles but do not affect negative values. Soffits exhibit the highest 𝐶𝑝 values at their edges, while fascia experience lower 𝐶𝑝 values in comparison. The strongest suction forces occur under the roof | ||
