Abstract: The Applied Technology Council has initiated the ATC-58 project to develop next-generation performance-based seismic design guidelines applicable to the design of new buildings and upgrade of existing buildings. The guidelines will enable: design of buildings capable of better or more reliable performance than code-based procedures; provide a rational basis for the design of structures using new technologies and structural systems; and provide a means of improving the reliability and effectiveness of current building code procedures. Performance will be expressed directly in terms of the probable financial, human, and occupancy interruption losses caused by earthquake damage. Performance may be expressed as expected losses, given specific design events, average annual values, considering all events that may occur and the probability of each, or probable maximum losses over a given time interval, as best suits the decision-making style of individual stakeholders. Performance assessment procedures employed by the guidelines are based on the framework developed by the Pacific Earthquake Engineering Research Center. Though primarily intended to guide the design of buildings to resist the effects of earthquakes, the guidelines are intended to be compatible with performance-based design procedures currently under development by others to address, fire, blast and other extreme hazards. The ATC-58 project is funded by the Federal Emergency Management Agency.
