“…To study the peculiarities of the dynamic impact of moving loads on bridge structures in modern conditions, existing approaches become insufficient, and dynamic calculation methods need to be improved and developed. All this confirms the importance and relevance of solving the problem of changing the dynamic responses of transport structures to moving loads [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

The article deals with the vibrations of a reinforced concrete bridge whose supports are located in soils with different properties under the action of overweight cargoes. The assumption is made that the structure deformed in the elastic zone when Hooke's law is valid. The Fourier method is used to solve the problem. The results are presented as graphs of changes in stresses and deflections along the coordinate and time, which are accompanied by analysis. When a concentrated load is applied, depending on the stiffness coefficient of the connection between the supports and the ground, stresses exceeding the limit load can occur in the middle of the beam cross-section. Thus, in the calculations, it is necessary to consider the nature of the interaction of the supports with the surrounding soils when calculating the beams for the action of moving loads.
