Abstract: The finite element method was used to build a finite element model for the external prestressed simply supported steel beam to simulate dynamically the natural frequencies of the beam under different prestress forces and different prestressed reinforcement eccentricity arrangements. Based on the results, the behavior and the extent of the effect of the prestress force on the natural frequencies were analyzed and the quantitative relations between the prestress force and the natural frequencies of the bridge were obtained, giving a theoretical support for the idcntitication of the effective prestress force in the prestressed simply supported beams.

Key words: road engineering, prestressed simply supported beam, natural frequency, prestress force, finite element method
