Seismic resilience of typical code-conforming RC moment frame buildings in Canada

This article examines the baseline resilience of reinforced concrete (RC) moment frame buildings conforming to seismic design standards Canada. Metrics for robustness, rapidity, and are evaluated capture system’s reliability, speed recovery, socioeconomic impacts. Buildings different heights using nonlinear time-history analyses. Six damage states defined as disjoint branches an event tree depending on building’s path recovery. For a scenario earthquake magnitude 7.3 at distance 30 km from Vancouver, housing occupancy recovery trajectory is developed. Monte Carlo simulations used propagate uncertainty hazards building response lead time required found maintain 50%–65% their pre-event in immediate aftermath. The restored 90% within 2–4 months, with shorter period low-rise buildings, whereas system level requires 6 months 1 year restoration 90%. Empirical data Loma Prieta (1989) Northridge (1994) earthquakes compare analytically predicted repair times. findings this will facilitate shift resilience-based
