NCHRP Report 654 establishes a user's manual for the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. The report also proposes revisions to the AASHTO LRFD Bridge Design Specifications and provides recommendations to develop improved crack control reinforcement details for use in new girders. The material in this report will be of immediate interest to bridge engineers.
The objective of this project was to establish procedures for the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. A user's manual for the application of these procedures was prepared.
This research was performed under NCHRP Project 18-14 by the University of Nebraska – Lincoln with the assistance of the George Washington University, Washington, DC.
