ARTICLE ANNOTATION

quote
The article considers the influence of the pliability of support links for automobile bridges with beam spans under dynamic loads. The calculation scheme and mathematical model are given. The results of research on a four-span automobile overpass are presented. The natural frequencies and waveforms, bending moments and maximum deflections, as well as the dynamic coefficients for changing the translational and rotational stiffness of the supports, are obtained. The influence of heavy transport on the stressed state of an overpass is considered. Recommendations on the load-bearing capacity of overpasses when changing support rigidity, as well as on design limitations for practical solutions, are provided. A discussion of the results and relevant conclusions is presented.
