Abstract
The use of heat straightening to repair damaged steel bridges requires careful planning and design of the repair. This planning begins with the engineer, who provides guidelines for both supervision and implementation of the repair through the supervisor and contractor. The process begins with damage assessment and includes checking for fractures, measuring the degree of damage, evaluating the degree of material degradation, and checking geometric distortion. The second step is to plan the repair by analyzing the degree of damage, determining maximum strains, selecting heating patterns, and developing a constraint plan. A methodology is provided for this planning and design. In addition, the responsibilities of the supervisor and the contractor are given. Practitioners are primarily targeted and guidelines are provided for implementing heat-straightening repairs.
