Rating and Evaluation of Existing Steel Bridges [B25]

While most older bridges were designed with allowable stress design, modern evaluation is now performed using the AASHTO Manual for Bridge Evaluation (MBE) which uses load and resistance factor methods. Existing bridges may exhibit deterioration that can affect their strength, but methods to include condition states in quantitative evaluation tasks are lacking. This session provides new tools for evaluating steel bridge members and connections. It includes MBE-compatible calibration of resistance models for steel pin and hanger connections and details methods to account for corrosion damage in evaluating steel girders.
