TORNADO DESIGN WINDS BASED ON RISK

A procedure is presented for evaluating the probability of damage due to tornado wind velocities above a specified threshold. It implements theoretical velocity profiles to convert reported damage width data at low velocity thresholds to damage widths for velocities that might cause structural damage. A stationary uniform arrival process with geographically dependent rate is used along with joint statistical properties for damage width, damage length, peak wind velocity, and direction of travel. Design curves for evaluating the damage likelihood and examples of their application are included. A critical analysis of the procedure is also presented.
