Notes:
Owners and designers of buildings should have a means of executing performance-based engineering for both seismic and wind effects, whereby multiple wind speeds are established based on a "risk-consistent" set of probability levels. While this approach requires hazard and structural analysis methods beyond the prescribed code, it can result in enhanced levels of structural performance, greater total reliability, or greater economy in design and protection of economic value. In addition, when applied to wind design, performance-based engineering can address issues of occupant comfort and serviceability for more frequent environmental conditions. It would also be a rational means of comparing wind and seismic hazards and structural performance levels with risk consistency
