The purpose of this study is to determine the rational use areas of various computational models types while dynamic analysis. This topic is relevant because of the need to carry out precise dynamic calculations for structures at the high-speed rail, in order to ensure the design of a reliable structures. The object of the study is a single-span girder for the high-speed rail. Research methods are numerical analysis using various models; modal calculation of the oscillation shapes and frequencies; comparative analysis. The result of this study are recommendations on the areas of rational use of various types of models.
