During this process of the project, five groups of modellers (that had already contributed to Phase III) agreed to exchange the structural model and vulnerability data on construction typologies that were derived by each of them separately in the previous phase and to perform vulnerability analyses (using their own procedures) on data provided by the other groups. Capacity and fragility curves were developed for concrete and masonry buildings that do not comply with the HAZUS typologies, either because they are not designed to code standards or because the construction details substantially differ from U.S. code provisions.
