A Functional Approach for the Analysis of Peak Wind Loads on Houses Exposed to Hurricanes and Validation of Wind Tunnel Simulations

摘要

Field data collected under the Florida Coastal Monitoring Program (FCMP) during recent hurricane seasons on prototype buildings has revealed that measured pressure coefficients exceeded the provisions of building codes and that wind damage occurred at wind speeds well below the design wind speeds presented in these codes. Because the current code provisions for wind loads are based on the reduction of many wind tunnel observations into a few numbers, the question arises as to what constitutes a proper wind tunnel simulation of the flow in the atmospheric surface layer and associated wind loads on low-rise structures and what procedures should be followed in translating pressure coefficients as measured in these simulations to full scale applications.
