Synopsis Heat-straightening Repair of Damaged Steel Bridge Girders by : Robert J. Connor
TRB¿s National Cooperative Highway Research Program (NCHRP) Report 604: Heat-Straightening Repair of Damaged Steel Bridge Girders: Fatigue and Fracture Performance explores limits, based on fatigue and fracture performance, on the number of damage and repair cycles to which damaged steel bridge girders may be subjected using the heat-straightening procedure.

Synopsis Synthesis Study: Heat Treatment and Its Effects on Rehabilitating Steel Bridges in Indiana by : Matthew Lackowski
Significant research has been conducted on the development of: (1) heat straightening repair techniques and their field implementation, (2) guidelines and recommendations for heat straightening repair, (3) empirical procedures for estimating plastic rotations achieved during heat straightening, (4) empirical procedures for predicting residual stresses caused by heat straightening, and (5) the effects of heat straightening on the structural properties of repaired bridges. Currently, there is a need for additional research on: (a) the fatigue performance of heat straightened beams, (b) the effects of single and multiple heat straightening on the fracture toughness and microstructure of steel beams, (c) the development of guidelines for evaluating and replacing steel beams subjected to single or multiple damage-repairs, and (d) investigating the effects of realistic heat straightening with imperfections on the properties and serviceability of steel beam bridges. The literature review of existing heat treatments indicates that heat straightening with maximum temperature limited to 1200 F is relatively similar to the process annealing heat treatment. Heat straightening with maximum temperature limited to 1400oF is similar to the normalizing annealing heat treatment. Both these heat treatments repair plastically deformed microstructure by the phenomenon known as recovery and recrystallization. Normalizing annealing is more efficient and faster than process annealing in repairing the plastically deformed microstructure by recrystallization. Heat treatment and repair of the material microstructure is incidental to the heat straightening repair process. The heat straightened beam can be further heat treated to complete the repair of the material microstructure (recrystallization etc.). The practical and economic feasibility of additional heat treatment using electrically powered and controlled radiant heaters was evaluated and found to be reasonable.

Synopsis Risk-Based Bridge Engineering by : Khaled Mahmoud
Risk-based engineering is essential for the efficient asset management and safe operation of bridges. A risk-based asset management strategy couples risk management, standard work, reliability-based inspection and structural analysis, and condition-based maintenance to properly apply resources based on process criticality. This ensures that proper controls are put in place and reliability analysis is used to ensure continuous improvement. An effective risk-based management system includes an enterprise asset management or resource solution that properly catalogues asset attribute data, a functional hierarchy, criticality analysis, risk and failure analysis, control plans, reliability analysis and continuous improvement. Such efforts include periodic inspections, condition evaluations and prioritizing repairs accordingly. This book contains select papers that were presented at the 10th New York City Bridge Conference, held on August 26-27, 2019. The volume is a valuable contribution to the state-of-the-art in bridge engineering.
