Implementation of the modern International Building Code and ASCE wind standards in Hawaii requires an empirical evaluation of the Kzt topographic and Kd wind directionality terms that are an integral part of the ASCE-7 standard, so that they can be adapted for use in the complex terrain of the island of Oahu in the State of Hawaii. The ASCE Standard 7-02 [1] specifies the following equation for velocity pressure: q = 0.00256 Kz Kzt Kd V2 I where: Kz is the velocity pressure exposure coefficient that is defined according to system or component design cases and terrain category (B, urban, suburban or wooded or C, flat, unobstructed, open terrain without substantial development), Kzt is the topographic speed-up factor, Kd is the wind directionality factor which accounts for the fact that the probability that the maximum wind may not impact the structural component or system in its weakest orientation, V is the peak gust windspeed associated with a 500-year return period, divided by √1.5, and I is the Importance Factor of the building or structure, based on its occupancy type, which functions as an implicit adjustment factor to the return period. The project is making several needed technical modifications so that wind-tunnel-based research results can be used by structural engineers in design applications through the ASCE 7 Analytical Method:
