Abstract
This thesis is a study on dynamic response characteristics according to natural frequency ratio between the upper structure and substructure of dome structures. A study investigates the dynamic response changes of dome structure according to property changes of substructure. The upper structure of shape variables sets up half-open angle and is modeled as ribbed-dome and latticed-dome. By standarding the first natural frequency of the upper structure having no substructure, the first natural frequency of substructure is changed as identical ratio. The natural mode shape and frequency were analyzed through eigenvalue analysis.
