Vibrations of a rigid beam elastically connected to deformable supports under seismic loads

Abstract

In practice, there are problems related to the calculation of groups of piles buried in the ground environment with different depths of immersion. At the same time, the main attention is paid to assessing the influence of the external ground environment on the magnitude of pile movement and the development of contact forces at the points of connection of piles with load-bearing beams is evaluated. As the results of monitoring the condition of bridge structures under the action of external forces, especially seismic ones, show, the greatest structural damage occurs at the junction of piles with beams. The oscillatory process of a rigid beam in contact with two piles through elastic elements is studied. The influence of stiffness coefficients on the frequency response of beam vibrations is estimated.
