dc.description.abstractIn this paper an analysis methodology is developed to evaluate the dynamic response on highway bridge decks due to vehicles crossing on the rough pavement surfaces. The analysis methodology follows a statistical model running in the time domain. The mathematical model simulates the bridge structure and the vehicle series as a system, the vehicle-bridge system. The bridge deck follows a straight beam model made discrete by finite elements and nodal concentrated masses, with vertical translations and in-plane rotations as degrees of freedom. The vehicle simulation uses concentrated parameters of mass, stiffness and damping. Four different types of vehicles are modelled as rigid masses connected by springs and dampers with one, two, four or five degrees of freedom. According to each vehicle model, translational and rotational displacements are considered. The deck surface roughness is defined by a weakly stationary, second order and ergodic random process based on a well-known power spectrum density of road pavement profiles. The moving load is modelled by an infinite series of equal vehicles, regularly spaced, and running at constant velocity. Only steady-state response is considered. Response data are produced on reinforced concrete highway bridge decks made of a straight box girder cross section based on several spans and support arrangements. Conclusions are concerned with the fitness of the developed analysis methodology and the mathematical model adequacy. The influence of the vehicle type on the highway bridge decks dynamic behaviour was observed. The magnitude of the effects due to the interaction of the vehicles with an irregular pavement surface and their consequences about design and maintenance are investigated.
