PROBABILITY OF FACILITY DAMAGE FROM EXTREME WIND EFFECTS

A probabilistic methodology has been developed for estimation of the probabilities of wind-induced damage to facilities. Mathematical models have been developed to describe each event in the wind hazard strike sequence, and they have been linked together to form an integrated simulation methodology. The models are based on data related to wind hazards, missile characteristics, and wind-borne missile impact tests. Probabilistic Monte Carlo techniques are used to generate the probability estimates in a full distribution analysis. Site-specific information on facility layout, missile sources and wind frequencies are required. 3-dimensional steady-state windfields are modeled and time-history calculations of missile trajectories are used to predict the loading distributions on each structure. The model may be used for component and system damage probabilities for different levels of design protection and, for existing facilities, optimal upgrade and risk-reduction strategies.
