• Abstract:
  This report summarizes over four years of research on heat-straightening repairs and provides a prototype engineering guide for the application of heat-straightening to bridge structures. It is based on the research results detailed in a companion report entitled, "Development of Engineering Design Procedures for Heat-Straightening Repair of Damaged Structural Steel for Bridges." This guide is not complete. In particular, repair of localized damage is not addressed. However, methods are provided for implementing procedures for repairing specific cases of global damage. ; The guide is written in specification format and can be used or incorporated into technical specifications for heat straightening. In addition to a general section, other sections include: damage assessment, material assessment, design of repair sequence, and field supervision of repair. ; The report concludes with a summary of the research project upon which guide is based. Major conclusions of the research as well as recommendations for future research are presented.
