Recently, natural disasters such as earthquake, tsunami, typhoon and tornado are increasing, and cause huge economical loses and victim. Thus, when the disaster occurs, it is important to prepare emergency evacuation shelters for fast and easy construction compared to general building system. And, deployable structures will provide a great help for such aim. Deployable structures have the great advantage of being faster and easier to erect and dismantle compared to conventional building forms. In this study, we confirm the possibility of deployment for shelter structures using scissor structure system. First, Basic model was performed to recognize the appllicability of the deployable systems of the dome-shaped structure. Second, Advanced model that more improved inner space and deployment mechanism was confirmed.

This research is an experimental study attempting to use MR-dampers to control the complex behavior of multi-span bridge structures due to external loads such as seismic loads. For the purposes of this study, the model of components in each structure is identified, and then based on the results, a simplified system of the structure is derived. The performance of MR-dampers for complex behavior control is evaluated separately, according to the self-performance of MR-dampers and according to the performance based on applications of control algorithms. Based on the simplified system, Lyapunov control algorithm and Clipped-optimal control algorithm are applied. As a result, MR-damper is proven to be effective in the complex behavior control of multi-span bridge structures.
