“…Most of vehicle models presented in many papers are simpler and smaller than this work. For example, two axles vehicle models are considered by Azimi et al (2013), Gonz alez and Mohammed (2018), Oliva et al (2013), andZhong et al (2015). Three axle models are also presented by Gonz alez and Mohammed (2018) and by Ma et al (2019).…”

PurposeRealistic composite vehicles with 2, 3, 5 and 9 axles, consisting of a truck with one or two trailers, are addressed in this paper by computational models for vehicle–bridge interaction analysis.Design/methodology/approachThe vehicle–bridge interaction (VBI) models are formed by sets of 2-D rigid blocks interconnected by mass, damping and stiffness elements to simulate their suspension system. The passage of the vehicles is performed at different speeds. Several rolling surface profiles are admitted, considering the maintenance grade of the pavement. The spectral density functions are generated from an experimental database to form the longitudinal surface irregularity profiles. A computational code written in Phyton based on the finite element method was developed considering the Euler–Bernoulli beam model.FindingsSeveral models of composite heavy vehicles are presented as manufactured and currently travel on major roads. Dynamic amplification factors are presented for each type of composite vehicle.Research limitations/implicationsThe VBI models for compound heavy vehicles are 2-D.Social implicationsThis work contributes to improving the safety and lifetime of the bridges, as well as the stability and comfort of the vehicles when passing over a bridge.Originality/valueThe structural response of the bridge is affected by the type and size of the compound vehicles, their speed and the conservative grade of the pavement. Moreover, one axle produces vibrations that can be superposed by the vibrations of the other axles. This effect can generate not usual dynamic responses.

“…The vehicle parameters and their variability are taken from [12], for the realisation of Monte Carlo simulations. The values of the vehicle parameters are mainly based on European 5-axles trucks and adopted from [38,39]. This study utilises the 5-axle truck model because it is arguably the most frequent heavy vehicle found on European roads.…”

“…There are four basic structural systems: simple girder bridges [3], cantilever girder bridges, continuous girder bridges [4], and rigid bridges. Compared with simple girder bridges and cantilever girder bridges, continuous girder bridges involve a reduced number of expansion joints and an improved linearity and smoothness of the bridge, while rigid bridges involve consolidated main girders and piers, a reduced number of bearings, and a lowered bridge maintenance cost.…”

Assembly construction is the main feature of industrialized bridges, and π-shaped section steel–concrete composites that are continuously rigid have been widely used in engineering fields in recent years; however, their dynamic responses and corresponding impact coefficients in positive and negative moment regions need to be further studied. First, considering the interface slip model, we established a finite element model for the π-shaped continuous region section of the steel–concrete composite on the Sutai Expressway Tongfu No. 3 viaduct. Second, the bridge deck unevenness parameters were generated by preparing a MATLAB program with random calculations and were added to the bridge deck as the excitation load along with the vehicle load. Such parameters are defined on the basis of considering the vertical degrees of freedom of the four wheels and of one vehicle rigid body. Finally, we analyzed the displacement or stress impact coefficients as the dynamic response index of the bridge by adjusting the vehicle travel speeds, vehicle weights, interface slip stiffness values, and deck unevenness values. The results show that the change in vehicle travel speed and the change in vehicle load weight have some influence on the change in the dynamic effect of the combined beam, but this change is not significant. Moreover, the unevenness and interface slip strength changes have a large effect on the dynamic effect of the combination beam, which can significantly change the impact coefficient of the combination beam bridge. The worse the unevenness of the bridge deck is, the lower the grade of interface slip for the steel–concrete composite bridges and the higher the impact coefficient. We calculated the recommended impact coefficient values of the steel–concrete composite bridge based on the specifications for various countries, and they range from 1.16 to 1.4; such values are similar to the finite element calculation results.
