“…This recommendation was followed by many researchers (Marchesiello et al 1999;Bogsjö et al 2010;Coussy et al 1989;Kamash and Robson 1978;Uyls et al 2007). In a more detailed analysis, (Captain et al 1979;Chang et al 2011;Camara et al 2014) employed a disk model with a rigid tread band that considers explicitly the wheel dimensions and its filtering effects. The selection of the cut-off limits should be related to the structure and the vehicle considered.…”

“…A number of recent filed measurements and theoretical investigations showed that vehicle vibration-induced pavement loads are moving stochastic loads [4][5][6][7][8]. The researchers concluded that vibrations of vehicles were related primarily to pavement surface roughness, vehicle velocity, and suspension types [9][10][11][12][13].…”

“…Since pavement loads are caused by vehicle vibration, it is necessary to include the vehicle in the investigations of pavement loads. Employing MIT heavy truck simulation program Hedric and his associates, Abbo and Markow [9][10][11], examined the influence of joint spacing, step faulting, vehicle suspension characteristics, and vehicle velocity on pavement damage as defined by fatigue cracking in concrete slab. The response of pavement under their consideration is achieved using PMARP, a static finite element program for pavement analysis developed by the Purdue.…”

This article lays out a unified theory for dynamics of vehicle-pavement interaction under moving and stochastic loads. It covers three major aspects of the subject: pavement surface, tire-pavement contact forces, and response of continuum media under moving and stochastic vehicular loads. Under the subject of pavement surface, the spectrum of thermal joints is analyzed using Fourier analysis of periodic function. One-dimensional and two-dimensional random field models of pavement surface are discussed given three different assumptions. Under the subject of tire-pavement contact forces, a vehicle is modeled as a linear system. At a constant speed of travel, random field of pavement surface serves as a stationary stochastic process exciting vehicle vibration, which, in turn, generates contact force at the interface of tire and pavement. The contact forces are analyzed in the time domain and the frequency domains using random vibration theory. It is shown that the contact force can be treated as a nonzero mean stationary process with a normal distribution. Power spectral density of the contact force of a vehicle with walking-beam suspension is simulated as an illustration. Under the subject of response of continuum media under moving and stochastic vehicular loads, both time-domain and frequency-domain analyses are presented for analytic treatment of moving load problem. It is shown that stochastic response of linear continuum media subject to a moving stationary load is a nonstationary process. Such a nonstationary stochastic process can be converted to a stationary stochastic process in a follow-up moving coordinate.

A method for the calculation of dynamic response and loading of single span multigirder bridges due to vehicle loads is described. The analysis takes account of vehicle acceleration or braking, road surface roughness and eccentric placement of the vehicle on the bridge. The analysis is presented for a three‐axle tractor‐trailer vehicle and the bridge is modelled as an orthotropic plate using higher order finite strips. As an example application, the loadings produced with braking of the three‐axle vehicle and a nominally equivalent two‐axle vehicle on a bridge were computed. Previous theoretical studies of bridge loading with vehicle braking had employed a two‐axle idealization of a three‐axle vehicle. The results of the present study show that this approximation is not valid for braking studies as the behaviour of the two vehicle models is significantly different. The loadings produced by a three‐axle vehicle are generally less severe than those due to an ‘equivalent’ two‐axle vehicle.
