A BASIC STUDY ON NONLINEAR BEHAVIORS OF RESPONSE CONTROLLED STRUCTURE IN CHAOTIC DYNAMICAL SYSTEM

摘要

This paper describes fundamental issues on responses of the new type of structures governed by nonlinear equations using one mass system with nonlinear histeretic curves. Differential equations with terms on nonlinear restoring forces idealized by hard and soft springs were solved directly by Uunge-Kutta method and the numerical results were compared with those acquired approximately by combination of linear equation and equivalent spring.
