Implementation Project: Strengthening a Continuous Steel Girder Bridge in Lakeport, Texas with Post-Installed Shear Connectors: Phase 1– Bridge Strengthening Design and Load Testing
In Implementation Project 5-6719, a non-composite continuous steel girder bridge located in Lakeport, Texas will be strengthened using techniques developed in TxDOT Research Project 0-6719. This strengthening technique involves the use of post-installed shear connectors in positive moment regions and the allowance of limited flexural yielding in negative moment regions. This Implementation Project is intended to demonstrate the strengthening technique, evaluate potential difficulties in design and construction and suggest solutions, and evaluate structural effectiveness and cost effectiveness of this bridge strengthening technique. Phase I of the Implementation Project includes selection of a non-composite continuous girder bridge in Texas for strengthening, detailed design of the strengthening system, detailed finite element analysis of the un-strengthened and strengthened bridge designs, and field load testing of the un-strengthened bridge to obtain baseline data on the behavior of the existing bridge for later comparison with field load testing data for the strengthened bridge. Phase II will include monitoring construction operations during the installation of post-installed shear connectors, collecting information on construction costs and difficulties, and field load testing of the bridge after strengthening is completed, to verify the effectiveness of the strengthening system.
