Transverse vibrations of load-bearing longiyudinal beams of transport structures
Abstract
The safety and reliability of transport structures depends on their dynamic characteristics, which affect the reserve of strength and rigidity. The purpose of these studies is to develop models and algorithms for more accurately determining the dynamic characteristics of load-bearing beams of transport structures at various interfaces with support connections. A calculation scheme and mathematical models have been developed. The results of dynamic calculations of reinforced concrete beam structures of highway overpasses using analytical and numerical calculations, as well as instrumental measurement data are presented. The values of the natural frequencies of transverse and longitudinal vibrations on the example of a road overpass are obtained, and forced vibrations under the influence of moving loads were also considered. An assessment of the stressstrain state of the beam structures of the overpass and recommendations for bearing capacity are given
