Development of a Continuous for Live Load Prefabricated Steel Accelerated Bridge Construction (ABC) Unit for Texas Bridges
The overall goal is to develop a system where prefabricated steel accelerated bridge construction (ABC) unit perform continuous for live load. The system must be: easily constructible, fast to assemble, durable long-term, safe, and cost-effective. The research teams will conduct a literature review to first synthesize what has been done by state departments of transportation and other agencies. The research teams will also evaluate the behavior of related TxDOT bridges through visual inspection and monitoring. The research teams will perform a system development program utilizing this information in conjunction with expert feedback from an Industry Review Panel (IRP) workshop (including the TxDOT Panel). The three (3) best system designs shall be selected for full-scale laboratory testing followed by an analytical parametric study. The research teams will compile and present the results at an IRP meeting with the TxDOT, where the final system shall be selected. The research teams will develop full Microstation details and specifications along with a user-friendly design guide. The guide shall identify the following: (1) Span length capabilities for girder sizes/depths/spacings. (2) General details for establishing live load continuity. (3) Closure pour details at interior bents and how to achieve acceptable deck stresses. (4) Structural steel splice details and acceptable tolerances. (5) Bearing layout to meet TxDOT substructure details.
