Characteristic Dynamic Increment for Extreme Traffic Loading Events on Short and Medium Span Highway Bridges
O'Brien, Eugene J.; Cantero, Daniel; Enright, Bernard; González, Arturo
More accurate assessment of safety can prevent unnecessary repair or replacement of existing bridges which in turn can result in great cost savings at network level. The allowance for dynamics is a significant component of traffic loading in many bridges and is often unnecessarily conservative. Critical traffic loading scenarios are considered in this paper with a model that allows for vehicle–bridge interaction and takes into account the road surface condition. Characteristic dynamic allowance values are presented for the assessment of mid-span bending moment in a wide range of short to medium span bridges for bidirectional traffic. Deposited by bulk import
