NCHRP 10-71 [Final]

Evaluation of CIP Reinforced Joints for Full-Depth Precast Concrete Bridge Decks

  Project Data
Funds: $650,000
Research Agency: University of Minnesota
Principal Investigator: Catherine French
Effective Date: 7/5/2006
Completion Date: 1/31/2011

The NCHRP Web-Only Document 173 covers two very different systems: (1) the precast composite slab-span system (PCSSS), which is an entire bridge system, and (2) transverse and longitudinal cast-in-place connection concepts to transfer moment and shear between precast deck panels and the flanges of precast decked bulb-Ts. The material in this report will be of immediate interest to bridge engineers. A summary of the research specific findings that emphasize how the research may be used is published in the NCHRP Research Results Digests 355.
The research was performed under NCHRP Project 10-71 by the University of Minnesota - Twin Cities and the University of Tennessee - Knoxville. The objectives of this research were to (1) develop specification language and commentary for recommended changes to the AASHTO LRFD Bridge Design Specifications and the AASHTO LRFD Bridge Construction Specifications, and (2) provide design examples for the design and construction of durable cast-in-place (CIP) reinforced concrete connections for precast deck systems that emulate monolithic construction.
