Author: Robert J.Connor, Michael J.Urban, Eric J.Kaufmann | Size: 10.75 MB | Format: PDF | Publisher: NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM | Year: 2008 | pages: 140 | ISBN: 9780309099370

This report summarizes the results of a project to establish 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. A key product presented here is suggested revisions to the Federal Highway Administration (FHWA) manual of practice for heat straightening. The report will be of particular interest to engineers in state highway agencies and industry responsible for bridge maintenance and repair.
