Abstract:

This Guide provides information to load rating engineers in the application of Modified Compression Field Theory (MCFT) when load rating concrete bridges in shear. It includes a literature review of recent research on load rating and summarizes a research study on the effects of minimum shear reinforcement amounts relative to load rating. This Guide also highlights the differences in design and load rating with MCFT. Presented are flow charts with three potential controlling cases of shear strength and procedures to ascertain the limiting shear strength for a concrete element. Load rating examples are provided, illustrating the application of AASHTO provisions f or shear load rating for three concrete bridges.
