Stress-Laminated Wood Bridge Decks: Experimental and Analytical Evaluations

摘要

The report presents results of recent research completed on solid wood stress-laminated decks. The primary objective was to quantify the behavior of the bridge decks when loaded with simulated truck loadings. Identification of an accurate analytical technique for predicting deck response and development of a new simplified prestressing anchorage system were also achieved. The objectives were accomplished through an experimental laboratory test program on full-size bridges followed by computer-aided analytical correlation studies. A summary of the project and experimental and analytical results is presented with conclusions and recommendations for tasks that should be completed before stress-laminated decks are used in bridge construction.
