AbstractThe paper presents selected aspects of dynamic numerical simulations of the steel railway bridge loaded by high-speed trains. The model of moving loads was assumed in accordance with the models set out in the applicable standards. The paper characterizes modern code requirements, in which the computer calculations of the dynamic response of the structure are the basis for assessing the suitability of bridges subjected to high speed trains (v >160 km/h). Computer calculations using the author's method of generating traffic loads in Abaqus FEM environment were carried out. It was 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 develop a plan to adapt this algorithm in order to generate traffic loads on bridges discretized as spatial and surface numerical models.
