Dynamical Response Analysis of a System with one Degree of Freedom Stresses by the Different Pulse Excitation Functions

Abstract

Viscoelastic systems embedded in structures such as bridges are subject to various dynamic loading from traffic. A dynamic study of these structures requires more accurate definition of disturbance function parameters: shape, duration and amplitude. This paper is a theoretical study that analyzes the dynamic response of a system with one degree of freedom with a viscoelastic element embedded (Kelvin rheological model) loaded by various functions of the excitation pulse. In this way it is highlighted the importance of the excitation function shape, in physical and mathematical modeling of technological systems.
