Performance and Improvement of Texas Poor Boy Continuous Bridge Deck Details 0-7013

The majority of Texas bridges are constructed with girders as simple spans with expansion joints that are sources for maintenance and durability issues. To avoid this, continuous decks are an attractive option, however, cracks may develop. TxDOT uses a detail that intentionally forms cracks, referred to as the “Texas Poor Boy” detail. TTI researchers developed candidate modifications to the current poor-boy details for new construction and candidate details for rehabilitation of existing bridges. Using the results of modeling and full-scale experimental tests, they made final recommendations for new design methodologies and details for continuous bridge decks.
