Support for AASHTO Committees and Councils. Roadmap to Update Bridge Deck Design Requirements
Design decisions have a direct influence on the performance of bridge decks and deck systems and need to be compatible with bridge owner construction, maintenance, and repair practices. Section 9 of the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications (BDS) addresses the analysis and design of bridge decks. The focus of Section 9 is on the information owners and designers need for the analysis and design of bridge decks on multiple types of bridges using a variety of bridge decks and deck systems. The current requirements for the analysis and design of bridge decks and deck systems have not been comprehensively updated since the adoption of the load and resistance factor design (LRFD) methodology in 1994. Research is needed to identify the steps for a systematic update of bridge deck design and analysis requirements. The objective of this research is to develop a roadmap to update bridge deck and deck systems design and analysis requirements.
