- Description
- Since 1973, California has mandated that “hospitals …which must be completely functional to perform
necessary services … after a disaster, shall be designed and constructed to resist, insofar as practical, the forces
generated by earthquakes…” With advances in performance-based design methodologies, nonlinear response
history analysis, and supplemental damping, engineers can better meet this legislated mandate.
This paper describes the analysis of a 94,000 sq. meter, high-rise urban hospital in California using steel moment
resisting frames with supplemental damping devices to control drift. Full-scale test results of Viscous Wall
Dampers and steel beam-column moment resisting connections are used to validate the Non-Linear Response
History analysis assumptions. The building seismic performance is evaluated using 10 strike-slip ground motion
records.
