| 摘要： | TRB’s National Cooperative Highway Research Program (NCHRP) Research Report 906 includes proposed revisions to the AASHTO LRFD Bridge Design Specifications minimum flexural reinforcement provisions for load and resistance factor design (LRFD) with detailed design examples illustrating the application of the proposed revisions. According to the AASHTO LRFD Bridge Design Specifications, minimum reinforcement provisions are intended to reduce the probability of brittle failure by providing flexural capacity greater than the cracking moment. There was a concern with the current American Association of State Highway and Transportation Officials (AASHTO) LRFD minimum flexural reinforcement requirements, especially when applied to pretensioned or post-tensioned concrete flexural members. A number of deliverables for the project are provided in three appendices to the contractor’s final report that are available online. They include the following: Appendix A: Test Girder Drawings, Appendix B: Design Examples, and Appendix C: Parametric Study Results. |
