This paper presents simulation analysis of load effects of bridges under random fleet. Based on actual data of vehicle loads on Guangzhou-Shenzhen Expressway and relevant statistical results, mid-span bending moments of long-span virtual simple-supported beams are calculated. Then probability distribution of the bending moments and extreme value distribution of the load effects within design reference period are obtained. Finally, characteristic values of mid-span bending moments and recommended values of design lane load are calculated, sequentially. The results studied in this paper can be as a reference for long-span bridge design, and also can be a reference for overloading control or weight charge policy.

Load Simulation

Based on the requirement for fatigue damage evaluation of long-span bridges, and existing research literatures, the vehicle type, vehicle weight and time duration are taken as characteristic parameters of random vehicle load. Taking the Second Nanjing Yangtze River Bridge as an example, the characteristics of traffic load are obtained by traffic investigation and the data from existing research results. In the paper the method and process for vehicle load spectrum simulation which includes data acquisition of random traffic load, statistical analysis and Monte Carlo simulation is proposed. The simulation program of random traffic flow is verified using the measured data. The proposed method can provide a reference for random traffic load simulation.
