Recording: Understanding the Principles and Procedures Behind ASCE 41

Garrett Hagen joined Degenkolb after completing his Master of Science from California Polytechnic University, San Luis Obispo, where his graduate research involved performance-based analysis of concrete structural walls. Garrett actively contributes to research regarding earthquake resilience and developing the state of practice for earthquake-resistant structures through several published papers, committee reports, and the development of ASCE 41.

Garrett was a member of post-earthquake reconnaissance teams that surveyed earthquake damage in Taiwan in February 2016 and Mexico City in September of 2017. Bringing back lessons from the earthquakes, Garrett assisted with writing guidelines for the Los Angeles ordinances for LA’s existing non-ductile concrete and soft-story buildings. He is also co-chair for the SEAOSC Existing Building Committee and Chair of ACI Committee 369-D which updates the ASCE 41 provisions for walls and coupling beams. Garrett’s portfolio includes design and seismic strengthening schemes for a variety of facilities.
