Abstract

Since vibration properties of a building structure were not easy to find out through a test, it was very difficult to in advance evaluate an influence of earthquake or other excitations on the building structure. However, currently, along with the development of the vibration analysis technique, it is possible to predict the structural performances of the buildings. The prediction of the vibration properties of the building structure has mainly employed a two-dimensional plane analysis so far, but not a three-dimensional analysis. The two-dimensional plane analysis encounters a reliability problem when the building is asymmetrical. This study has performed a three-dimensional modeling and vibration analysis on residential buildings when a subway passes below.

건축 구조물의 진동특성은 시험으로 알아내기가 어렵기 때문에 지진이나 다른 가진에 대한 영향을 미리 평가하기가 매우 어려웠다. 그러나 근래에 들어 해석 기술이 발전함에 따라 건축물에 대한 성능을 예측해 볼 수 있게 되었다. 건축 구조물의 진동특성 예측은 지금까지는 2차원 평면 해석이 주를 이루었고, 3차원 해석은 이루어지지 않고 있었다. 2차원 해석은 건축물이 비대칭일 때 해석의 신뢰성을 떨어뜨리는 문제를 안고 있다. 본 논문에서는 주거건축물을 3차원으로 모델링하였으며, 지하철 통과시 주거 건축물의 진동 해석을 수행하였다.
