| Abstract: |
The following topic is analyzed in this study: risks of exceeding the required levels of load capacity of reinforced concrete bridge superstructures due to the variability of operational traffic loads on bridges. Decrease of load capacity during operation is mainly due to the corrosion wear of the working reinforcement. The following types of risks of loss or decrease of load capacity are considered: undesirable – when restriction of the traffic on the bridge or reducing its durability is required; unacceptable – when termination of traffic on the bridge is necessary critical - the danger of a catastrophic collapse with possible human victims. During the entire period of operation, the exceedance probability of operating loads should not be lower than the one of the design load at the final stage of the bridge service. |
