Abstract
The performance of modern buildings with respect to protecting life safety in recent earthquakes (e.g., 1989 Loma Prieta, 1994 Northridge, and 2001 Nisqually) generally has been adequate. However, economic losses refl ecting damage-repair costs and temporary loss of use of buildings exceeded public expectations. Older buildings constructed with little or no consideration of seismic demands often performed poorly and, in some cases, created unacceptable risks to life safety; retrofi t of such buildings is possible but often expensive and disruptive. The building performance issues highlighted by these earthquakes have stimulated considerable interest in performance-based seismic design (PBSD).
