- Abstract:
- In order to analyze the dynamic response of pavement on long-span steel bridge decks under random dynamic loads, the irregularities of the pavement surface is simulated with the power spectrum density function, and the random load is calculated according to a vehicle vibration equation of vehicle model.The mechanical responses of three different cases are compared by using a transient dynamic analysis method, i.e., under random dynamic load, constant moving load and dead load respectively.The results indicate that the mid-span of two adjacent transversal diaphragms is the worst load position.The maximum vertical displacement and the maximum transversal tensile stress of the pavement are 1.33 times and 1.39 times as much as those when only considering the impact coefficients.This study not only provides a theoretical basis for the mixture design and structural design of pavement, but also puts forward higher demand on the construction and maintenance for steel deck pavement.
