The ATC-58 project seeks to develop the next generation of guidelines for performance-based seismic design and evaluation. This includes the development of seismic fragility functions for commonly employed building systems. These fragility functions define the likelihood that the system will exhibit a specific level of damage and thus require a specific type of repair when subjected to earthquake demand as defined by maximum story drift. The research presented here uses data from laboratory tests to develop fragility functions for one type of building system: reinforced concrete frames.
