Hurricane wind pressures on building components from
wind tunnel, field measurements, and CFD

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 (πΆπ) on the doors and windows (with and without shutters), soffits, and
fascia are compared against πΆπ values under ASCE 7-22 provisions. Results indicate that the πΆπ from field
measurements is localized and strongly dependent on wind direction in urban surroundings. Aluminium storm shutters
reduce positive πΆπ values on doors and windows at some angles but do not affect negative values. Soffits exhibit the
highest πΆπ values at their edges, while fascia experience lower πΆπ values in comparison. The strongest suction forces
occur under the roof
