Observations on ASCE 7-10 Methods for Determining Wind Loads

The purpose of this paper is to discuss methods for determining wind loads on buildings and other structures that warrant comment, correction or improvement. The assessment is intended to serve as a resource as a new version of the American Society of Civil Engineers ASCE-7 Standard is being prepared. Issues discussed in the paper include: wind speeds in non-hurricane regions; alternative analytical methods for determining wind loads and wind effects on Main Wind Force Resisting Systems and Components/Cladding; aerodynamic pressure coefficients; pressures on rooftop equipment; component and cladding pressures on arched roofs; and the wind tunnel procedure.
