| Abstract: | According to the existing vehicular load probability models,and based on the Monte-Carlo method,the vehicle random process was converted into many random variable parameters,such as the gross vehicle weight,vehicle length,vehicle space length etc.,then the load effect was simulated.Furthermore,a subsequent study in reference to the structural reliability features of the sub-healthy beam bridge,the vehicular load limit was obtained in this paper. |
