Abstract

The article presents results of the analysis of experimental-theoretical researches and dynamic tests of the composite steel-concrete superstructures of bridges in St. Petersburg, the Leningrad Region and the North-Western region of the Russian Federation. The authors analyzed the theoretical foundations of the coefficient of reduction of the calculated resistances γw, the real spectra of the forced vibrations of the most loaded elements, and made recommendations on the need to take into account the parameters that affect the actual dynamic loading and durability of bridge structures.
