The paper provides an overview of the current design methodology for wind load based on ASCE-7 (2002) and IBC (2003). In addition, an attempt is made to identify the issues in developing a performance-based design methodology for wind loading, in particular for reinforced concrete frame buildings. Explicit comparisons of wind and earthquake loading on structural systems are made to leverage a discussion for a performance based wind design methodology. It is demonstrated that significant differences in performance based design methodologies will exist due to the nature of the loadings and the different design philosophies. Future research is required on establishing criteria for appropriate performance objectives and performance levels during serviceability and strength loading conditions.
