Destructive Testing Of Composite Precast Concrete Deck Panels And Built-Up Steel Plate Girders, Wesley J. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Utah Department of Transportation (UDOT) has implemented the use of precast concrete panels for bridge deck construction. A bridge utilizing these panels as a reconstruction method was decommissioned three years after the new deck installation, due to unrelated matters. Two sections of this bridge were salvaged and sent to Utah State University (USU) for destructive testing.

Each bridge section consisted of two built-up steel plate girders intact with the precast concrete deck panels. The precast panels were designed and constructed to achieve full composite action between the deck and built-up steel plate girders through the use of Nelson shear …

Destructive Testing And Finite-Element Modeling Of Full-Scale Bridge Sections Containing Precast Deck Panels, Travis R. Brackus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Full-depth, precast panel deck systems are becoming more common in bridge installation and repair. The objective of these systems is to achieve the performance of cast-in-place systems while simultaneously saving time and money. The structural behavior of these systems has been the subject of scrutiny in recent research. The Utah Department of Transportation demolished a steel I-girder bridge containing a precast panel deck system and provided two full-scale specimens for this project. Destructive testing was performed at Utah State University on the specimens to investigate three failure modes: flexural, beam shear, and punching shear. Finite-element models were created using ANSYS …
