Abstract
The purpose of this paper is to study about dynamic instability characteristic of cable dome structures by Sinusoidal excitations. Cable dome is well-known among the cable dome structures that are the lightweight hybrid structure using compression and tension element continuously. Dynamic bucking process in the phase plane is very important thing for understanding why unstable phenomena are sensitively originated in nonlinear dynamic by various initial conditions. But there is no paper for the dynamic instability of hybrid cable dome by Sinusoidal excitations, many papers which deal with the dynamic instability for shell-structures under the step load have been published. As a result of Geiger-typed cable dome which shows behavior in dynamic nonlinear analysis with initial imperfection.
