Abstract:

This report explains in detail how to use the modified compression field theory (MCFT) for shear load rating of pretensioned concrete members. The report includes a summary of MCFT theory and application, possible shear failure mechanisms that may occur in pretensioned members, and a recently recommended methodology for an iterative process for using MCFT for shear load rating. Additional details and explanations are provided for application of this methodology for shear load rating utilizing MCFT for pretensioned concrete members. Details for a complete shear load rating example are provided for a pretensioned box beam at the critical section, the effective shear depth away from the face of the support, and along the length of the beam.
