“…The moving trains and bridges were assumed to be interacting through wheel-rail interfaces [4][5][6][7] or through the primary suspension system between wheelsets and bogies [8][9][10][11][12]. Zhang et al [13] recently established a wheel-rail contact model with pre-defined hunting movements of wheelsets.…”

“…There are various representations of moving rail vehicles used in dynamic analyses, differing in terms of mathematical and physical accuracy [2,6,7,8,9,12,16]. The most popular models are ( The first two models can be used for determining the dynamic response of bridge yet without analysing the behaviour of vehicle and vehicle-structure interaction.…”

The paper presents selected aspects of dynamie numerical simulations of an orthotropic steel raił way bridge loaded by high-speed trains. The model of moving loads was adopted in accordance with the models set out in the applicable standards. The current European code requirements are referred in which the computer calculations of the dynamie response of the structure are the bas is for assessing the suitability of the structure to carry high-speed raił traffic ( v > 160 km/h ). In this research the calculations are based on the author's method of generating traffic loads in Abaqus FEM environment. lt is emphasized in the paper that in most commercial FEM codes (including Abaqus), moving loads are not implemented in modules responsible for defining of loads. The author's approach to this issue allowed to obtain results confirming its adequacy. In the longer term, the authors will develop a plan to adapt this algorithm in order to generale traftic loads on bridges discretized as spatial and piane numerical models.
