TRB's National Cooperative Highway Research Program (NCHRP) Report 679: Design of Concrete Structures Using High-Strength Steel Reinforcement evaulates the existing American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications relevant to the use of high-strength reinforcing steel and other grades of reinforcing steel having no discernible yield plateau.
The report also includes recommended language to the AASHTO LRFD Bridge Design Specifications that will permit the use of high-strength reinforcing steel with specified yield strengths not greater than 100 ksi.
The Appendixes to NCHRP Report 679 were published online and include the following: APPENDIX A—Material Properties APPENDIX B—Flexural Resistance of Members with Reinforcing Bars Lacking Well- Defined Yield Plateau APPENDIX C—Strain Limits for Tension-Controlled/Compression-Controlled and Strains to Allow Negative Moment Redistribution APPENDIX D—Flexure Beam Tests APPENDIX E—Fatigue of High-Strength Reinforcing Steel APPENDIX F—Shear Beam Tests APPENDIX G—Analytical Studies of Columns APPENDIX H—Beam Splice Tests APPENDIX I—Crack Control APPENDIX J—Survey Results APPENDIX K—Design Examples APPENDIX L—Proposed Changes to Section 5 of the AASHTO LRFD Specification APPENDIX M—2010 AASHTO Bridge Committee Agenda Item
