The Live Load Response Of The Open Web Steel Joist Black Slough Bridge, Piero Caputo
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The bridge being studied spans the Black Slough River in the Nucor/Vulcraft facilities near Brigham City, Utah. The bridge is composed of seven heavyweight open web steel joists supporting a concrete deck-slab element and sitting in two concrete cantilever walls serving as bearings.
