Abstract

During the conduct of the ATC-63 Project, which was funded by the Federal Emergency Management Agency (FEMA) and resulted in the publication of the FEMA P-695 report, Quantification of Building Seismic Performance Factors (FEMA, 2009), it became apparent that the current "formulation" of seismic design parameters did not fully address the potential variation in collapse performance of buildings due to differences in building period, inelastic response capacity, and seismic design loading. Results from beta testing of the FEMA P-695 Methodology also supported the notion that the observed variation in collapse performance was important, and that alternative formulations of seismic design parameters were needed to ensure a uniform level of collapse risk for all building systems. In deciding on a recommended path forward, the project team first developed a list of preliminary reformulation concepts and related areas of needed technical investigation. This list was prioritized based on relative importance and relative potential for changing the way that design parameters relate to system collapse behavior. The following topics were chosen for study: (1) short-period systems; (2) overstrength; and (3) long-period systems. A conceptual framework for reformulation of seismic design parameters was developed using the findings from problem-focused studies and additional conceptual ideas from the project team.
