The Live Load Response Of The Open Web Steel Joist Black Slough Bridge, Piero Caputo
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. A full-scale live-load test was performed using forklift vehicles at four locations on the deck. During the test, axial strains, deflections, and rotations where measured.
In their provisions, the American Association of State Highway and Transportation Officials (AASHTO) included a simplified number of equations and solutions used to calculate GDFs for standardized decks supported by beam systems. …
Effects Of Short-Term Strains On Concrete Bulb-Tee Bridge Girders And Analysis Of The Practicality Of Using Three-Dimensional Models Based On Drone Imagery To Aid In Bridge Inspections, Justin M. Pace
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The University Transportation Center at Utah State University sponsors research through the Federal Highway Administration’s University Transportation Center Program. The purpose of this research is to advance technology and expertise in transportation-related fields. This includes research pertaining to bridge design, monitoring, and inspection (the focus of this research).
The first focus area of this research monitored short-term strains at the bottom of girders in a concrete bulb-tee girder bridge. The strains were caused by traffic loading and recorded using strain transducers attached to the bottom of each bridge girder. Patterns in the strain loading were monitored to draw conclusions about …
