Dissipative Deformation of Bridge Span Beams
Abstract
The paper presents with the problem of the energy dissipation of oscillatory processes within the internal and external boundaries of deformation. The dependency is obtained for the oscillation dissipation rate and the shear angle of stress vector and deformations. The Voight hypothesis allows constructing the dependence between the internal resistance and the rate of the system displacement. The problems of the system flexibility at the elastic and elasto-plastic stage are considered in this paper using the Karman principle. The conditions of the dissipation factor are identified for the bridge span beams at a stage of their dynamic loading.
