Study on simulation and prediction of bridge load effect based on the Rice formula

11926,11912,11927,vehicle load effect

Based on the weigh in motion data at a toll station on the Beijing-Zhuhai Expressway, the statistic analysis of vehicle load data was carried out. Monte Carlo method was used to generate random traffic flow, the maximum bending moment effect of 30m and 40m simple supported beams were obtained. The Rice formula was used for fitting and extrapolation, and the predicted value of the maximum bending moment of the supported beams were obtained. By comparing with vehicle load effect according to current specification, some reference provided for the specification of bridge load in our country.
