Earthquake Loss Estimation of Individual Buildings Based on Convex Set Model

Abstract eng:
Probabilistic results drawn upon inadequate information, as usually happen, are suspicious. The uncertainties of spectrum displacement, damage state medians and loss ratio are considered with the bound envelope convex set model, and a bound loss estimation method is derived by integrating HAZUS-AEBM module with the convex set theory. The loss estimation results of a hotel in southern China shows that the loss by HAZUS-AEBM method locates in the lower half intervals of convex analysis results. The PEER’s probabilistic loss estimation methodology is also applied to this hotel to demonstrate the benefits of the bound loss estimation method proposed in this study.
