| 摘要： | TRB’s National Cooperative Highway Research Program (NCHRP) Report 654: Evaluation and Repair Procedures for Precast/Prestressed Concrete Girders with Longitudinal Cracking in the Web explores the acceptance, repair, or rejection of precast/prestressed concrete girders with longitudinal web cracking. The report also examines suggested revisions to the American Association of State Highway and Transportation Officials’ Load Resistance Factor Design Bridge Design Specifications and measures to develop improved crack control reinforcement details for use in new girders. Appendices A through G for NCHRP Report 654 are available online. • Appendix A—Literature Review • Appendix B—National Survey • Appendix C—Structural Investigation and Full-Scale Girder Testing • Appendix D—Sealant Specifications • Appendix E—ASTM Specifications • Appendix F—Field Inspection of Bridges • Appendix G—Design Examples of End Zone Reinforcement |
