FRACAS

FRACAS is a fragility curve generator, based on the modified capacity spectrum method first developed by Rossetto & Elnashai (2005). FRACAS allows more sophisticated capacity curve idealizations, the use of various hysteretic models for the SDoF in the inelastic demand calculation, and the construction of fragility functions through several fitting techniques. The proposed approach is highly efficient and allows for fragility curves to be derived from the analysis of a specific structure or a population of frames subjected to a number of earthquake records with distinct characteristics. The method is able to account for the effect of variability in seismic input and structural characteristics on the damage statistics simulated for the building class, and evaluate the uncertainty in the fragility prediction.

BEA

This function implements the Bayesian emulation-based approach (BEA) to compute the probabilistic seismic response of buildings.

The BEA process is described in detail in the following document: Minas, S., Chandler, R.E., and Rossetto, T. (2018). "BEA: An efficient Bayesian emulation-based approach for probabilistic seismic response." Structural Safety.
