A Matlab-based seismic risk tool has been developed and named HAZUSICG.
Obviously this tool is still in development but it can provided damage results for the
general building stock of a city or country and also for the essential facilities as schools,
hospitals, emergency response facilities, etc. if they have provided as input file
(censuscenter.txt where the latitude and the longitude correspond to the location of the
facility).
The code has been written so it runs easily with some inputs from the user using the
keyboard. Uncertainties are included by running the code several times and changing
input parameters, so different output files are obtained which are multiplied by their
corresponding probabilities (weights of the branches of the logic tree) and treated with
the statistical tools of Matlab to get the median and standard deviation.
The input files are so transparent that they can be easily adjusted to any part of the world, just only taking into consideration the possibility of new model building types with other capacity and fragility curves. That’s an advantage with respect to HAZUS which has lower flexibility in terms of non-USA areas and building types.
The m-scripts which form HAZUSICG are commented so user can go through the lines
and easily change them if necessary.NORSAR; Universidad de Alicant
