100-Year Bridges: Design Practices and Performance Benefits of Hot-Dip Galvanized Steel (Archived Webcast)
Hot-dip galvanizing has been used as a means of corrosion protection for more than 150 years, and new technologies and creative chemistries continue to evolve the coating. As FHWA, state DOTs, and local municipalities strive to build the 100-year bridge, what role does hot‑dip galvanizing play? When best design practices are followed, hot‑dip galvanized steel can provide a sustainable and cost effective 100‑year bridge life.
This webcast will explore some of the specific design practices to avoid pitfalls such as warpage and distortion and connection points, as well as address new research on galvanized slip critical connections and the final report of the galvanized bolts on the Bay Bridge in Oakland, CA.
