    • Abstract:
      Corrosion of steel bridge beams due to deicing media is a very common problem in northern regions of the U.S. The deterioration of steel beam ends due to deck joint leakage and occasional spray from passing vehicles usually consists of irregularly shaped holes, termed section losses, which typically occur in the web near or directly above the bearing area. This may result in decreased shear capacity, web crippling, or web buckling. This report presents the results of a study sponsored by the Michigan Department of Transportation whose purpose was to provide the structural analyst with simplified methods for computing the reduced capacity of the section, i.e. determination of whether or not a bridge should be posted for trucks. The guidelines are based on the results of finite element analyses (FEA) for a suite of sixteen typical steel girder bridges. The most common shapes and locations for steel beam end deterioration were identified by reviewing detailed inspection reports for various bridges in order to develop a simulation matrix of corrosively damaged steel beams for finite element analysis. Bridge plans and inspection reports were used to identify the needed beam and slab dimensions as well. Analyses of the steel beam ends with simulated damage of various sizes and shapes were performed by using finite element software SDRC IDEAS and ABAQUS. Experimental work was performed on a selected beam to verify the validity of finite element analysis. Design charts were developed for various cases of damage based on FEA results. The structural analysis guidelines consist of factors used to estimate the reduced load capacity of the deteriorated steel beam from existing AISC capacity equations.
