Abstract

A technique is developed to estimate damage, loss, and post-earthquake operability for instrumented buildings shortly after the cessation of strong motion. The analysis modifies PEER's second-generation performance-based earthquake engineering (PBEE-2) technique to account for the additional information that strong-motion instruments provide. In the modification, Bayesian updating is used to update the prior probability distribution of the facility's structural characteristics. The outcome of the analysis is the estimated likely locations of physical damage (important for concealed structural damage); the probability distribution of repair cost (valuable for quickly arranging for financing); and a rapid pre-inspection estimate of safety and operability.
