지중파에 의한 지하 구조물의 부재피해평가를 위한 고속해석모델 적용 가능성 연구 = Feasibility Study on a Damage Assessment of Underground Structures by Ground Shock Using the Fast Running Model

다국어 초록 (Multilingual Abstract)

This study investigated applicability of the fast running model for damage assessment of underground structures by ground shock. For this reason, the fast running model that consists of two main models such as the ground shock generation and propagation model and the underground structural damage assessment model was developed. The ground shock generation and propagation model was programed using theoretical formula and empirical formula introduced in TM5-855-1(US army manual). The single degree of freedom model of structural components was utilized to predict structural dynamic displacements which are used as index to assess damage level of components. In order to confirm the feasibility of the developed fast running model, underground structural dynamic displacements estimated from the fast running model were compared to displacements obtained from the finite element analysis.
