Concrete Bridge Shear Load Rating, Synthesis Report

This report synthesizes the current state of practice in the shear load rating of concrete bridges. A brief overview of the historical approaches, encompassing the methods from the first to the latest AASHTO Specifications, to shear demand and resistance is presented. The overview includes load combinations, live load distribution, and shear strength in both reinforced and prestressed concrete. A historical overview of the bridge load rating is presented. The use of software in concrete shear load rating is also investigated. The study of current policies, practices, and challenges in concrete bridge shear load rating is conducted through a survey of nine state DOTs. An extensive literature review is performed to highlight recent and relevant research on concrete shear strength, concrete bridge behavior in shear and concrete bridge shear load rating. This synthesis report identifies recommendations on research, modifications to existing specifications and manuals, and the development of clear and concise guidance to practitioners.
