ABSTRACT
Optimum engineering decision criteria are presented for the establishment of repair and maintenance strategies for structural systems located at sites exposed to significant seismic hazard levels. Decisions are based on information about damage accumulation and on models about its impact on the seismic vulnerability functions of the systems considered. Damage estimates are assumed to be provided by structural health monitoring studies performed after the occurrence of moderate- and high-intensity earthquakes. The problem of transforming the latter studies into damage estimates and into the resulting seismic reliability functions is examined and some illustrative examples are presented for multistory buildings.
