(RMS) in California. This paper is the second of two that focuses on vulnerability function development, building inventory and economic exposure development and probabilistic loss estimation. The first paper focuses on hazard quantification. This paper describes procedures adopted in order to develop and implement building vulnerability functions to relate damage ratio (defined as dollar loss / replacement value) to spectra acceleration for individual building and building portfolio loss assessment. The Performance Based Engineering framework developed by the PEER researchers is implemented through the use of Incremental Dynamic Analyses (IDA) to develop the building vulnerability functions. Nine structure models, which represent a mix of Chinese building inventory, were designed using the Chinese building code. These structure models were subjected to roughly four hundred Chinese ground motions to perform non-linear dynamic analysis. The maximum inter-story drift of each story from time-history analysis is computed and related to a damage state and an associated damage ratio for both structural and non-structural components. In the development of fragility functions uncertainty associated with structural parameters and building damage thresholds were considered. This paper also highlights building inventory and exposure development, as well as the model calibration and validation process using key historical events such as the 1976 Great Tangshan earthquake for which good damage data is available.
