description: In the final qualification work, one method of modernization of the pedestrian bridge "Krasny Sudostroitel" was developed. In the Sofistic software package, the design and structural schemes of the existing bridge are designed, and the values of the natural oscillations are obtained. Next, dynamic tests are performed, which confirm the correctness of the design in the software package. Based on the obtained model, split structures of the bridge span structure that may arise during the operation of the engineering structure are developed. The calculation in the software for natural oscillations is made, the values of natural oscillations and their occurrence in the dangerous range are analyzed. A method for reducing the mass by using composite materials is proposed, and the periods of natural oscillations are calculated repeatedly with the changed mass. The results of the calculations are analyzed. The result of the work is the result of the fact that the use of composite materials in the flooring, to reduce the mass, is possible.
