NCHRP Report 721 provides proposed revisions to Section 7—Fatigue Evaluation of Steel Bridges of the AASHTO Manual for Bridge Evaluation with detailed examples of the application of the proposed revisions. The proposed revisions and examples were developed based on analytical and experimental research conducted to improve existing methods to evaluate and assess the serviceability of bridge structures for the fatigue limit state. The material in this report will be of immediate interest to highway design engineers.
The research was performed under NCHRP Project 12-81, “Evaluation of Fatigue on the Serviceability of Highway Bridges”, by a team led by Dr. Mark D. Bowman, the School of Civil Engineering at Purdue University in West Lafayette, IN. The objectives of NCHRP Project 12-81 were to (1) propose updates to Section 7—Fatigue Evaluation of Steel Bridges of the AASHTO Manual for Bridge Evaluation and (2) provide detailed examples of the application of the proposed revisions.
