수치해석을 이용한 운동학적 힘을 고려한 지하구조물 동적 거동 평가

초록

In this research, dynamic numerical analysis for underground structure was performed to evaluate dynamic behavior during earthquake. 3D model formulated in time domain to consider the non-linearity of soil utilizing Opensees, which is the finite element method program. In addition, SSI (soil-structure interaction) was simulated by adopting the pySimple1. Based on simulation results, it was found that geotechnical underground structure have moved with soil displacement. It means that not inertial force but kinematic load effect was dominant on dynamic behavior of underground structure.
