In this article, we consider a split beam (in the form of a prestressed hollow slab of bridge structures) on two supports with hinged fastening (hingedly supported), in order to study the natural frequencies and modes of oscillation, is also calculated depending on the length of the plate (i.e. small length of the span up to 15 meters). A review and analysis of engineering structures, as well as the selection of materials with the calculation of the height of the compressed zone of concrete, sections, diameter and number of reinforcement were carried out.
