This simple Matlab code demonstrates a proposed algorithm for producing simulations of partially dependent component damage in the FEMA P-58 performance assessment methodology.
The algorithm demonstrated here is described in the following document
Jack W. Baker, Ed Almeter, Dustin Cook, Abbie Liel, and Curt Haselton, (2023) "A model for partially dependent component damage fragilities in seismic risk analysis," Earthquake Spectra. (in press).
The results from this calculation are the "Simple Example" presented in the above manuscript.
MAIN_correlations.m is a script where the input parameters for the simulation are specified. The script correctly formats the parameters and then calls the analysis function.
fn_simulate_damage.m is the analysis function that performs the component damage simulations. Component damage realizations are produced, summary statistics are computed, and an annotated figure is produced to summarize the results.
