Impacts of design story-drift-ratio requirements and detailing practices on the life-cycle seismic cost and resilience performance of steel SMRF buildings in different seismic environments

Funding agency: National Research and Development Agency (ANID) Grant: FONDECYT Regular 1240503 (2025-2029) Principal Investigator: Gerardo Araya-Letelier Co-Principal Investigators: Rodrigo Astroza, Diego López-García Chilean code-conforming RC buildings have demonstrated outstanding seismic performance, with very low collapse rates, economic losses, and downtime, largely attributed to stringent design drift limits. However, applying the same drift requirements to steel…
