One of the indicators evaluate the bridge load bearing capacity is the peak impact factor. The peak impact factor is related to vehicle types and speeds and frequency of the bridges. Among the parameters, the vehicle types such as DB-24 and standard vehicle load presented in the current specification have different load distribution and different load axles space. Considering these features, in the present study, the variation of the peak impact factor according to each vehicle type is investigated and compared.
