NRCA's wind-load calculator
This month, NRCA is debuting its online wind-load calculator, www.roofwinddesigner.com. This Web-based application is intended to provide roofing professionals with an easy way to accurately determine roof systems' design wind loads for many commonly encountered building types subject to building code compliance.
ASCE 7, "Minimum Design Loads for Buildings and Other Structures," is a widely recognized consensus standard method for determining design wind loads on buildings and other structures. The 2005 edition of the standard, designated as ASCE 7-05, is referenced in and serves as the technical basis for wind-load determination in the International Building Code, 2006 Edition, and 2006 edition of NFPA 5000: Building Construction and Safety Code.
ASCE 7-05, Chapter 6—Wind Loads specifically addresses the determination of wind loads on buildings and other structures. Within the chapter, three methods of wind-load determination are provided and referred to as Methods 1, 2 and 3.
