Abstract

This paper describes results of the CSMIP-funded project to develop correlations of observed building performance with measured ground motion. Much of the information presented in the paper is taken from King et al. (2002), which described the progress of the project to date at last year’s SMIP02 Seminar. Motion-damage relationships in the form of lognormal fragility curves and damage probability matrices have been developed for wood frame, steel moment frame, and concrete frame buildings – building types for which there are enough samples in the database to warrant statistical analysis. The ground motion parameters that were found to exhibit relatively higher correlations with building performance were used in the analysis. Building performance is characterized in terms of damage states and performance levels. The resulting relationships are compared to those published in ATC-13 (ATC, 1985) and HAZUS99 (FEMA, 1999). The comparison shows that the relationships developed in the project are quite different from the published models; however, the loss estimates resulting from the application of the models are similar.
