Summary: | This two-day training course presents relevant issues related to fatigue and fracture in steel bridges, including analysis, design, evaluation, repair, and retrofit. It is based on the AASHTO LRFD Bridge Design Specifications, Eighth Edition, as well as the AASHTO Manual for Bridge Evaluation, Second Edition, with Interim Revisions through 2016. Participant Exercises, Guided Walk Throughs, and videos are included throughout the training to aid bridge engineers with the implementation of the presented information.
This course consists of three modules. The first module serves as a general introduction to the class. The second module covers fundamentals, and it includes four lessons - Introduction to Fatigue and Fracture, Crack Growth in Steel Structures, Theory, and Characterizing Fatigue and Fracture in Bridge Members. The third module covers application, and it includes five lessons - Analysis for Fatigue, AASHTO Design Approach for Fatigue, AASHTO Design Approach for Fracture, AASHTO Evaluation Approach, and Retrofit and Repair.
The curriculum materials include a comprehensive Reference Manual in CD format (FHWA Publication No. FHWA-NHI-16-016), lecture and workshop exercises intended to promote or enhance a working knowledge of AASHTO LRFD, and a participant workbook for lecture notes and exercises.
