dc.description.abstract | 지하철 운행하중에 대한 인접구조물의 효율적인 진동해석 방법에 관하여 연구하였다. 지반-구조물의 상호작용을 고려한 구조물의 동적해석을 수행하였으며, 지반의 내부영역과 외부무한영역을 각각 유한요소와 무한요소를 사용하여 구한 전체지반의 동적강성행렬과 지하철 운행하중효과를 구조물의 매립면으로 응축하여 인접구조물을 효율적으로 분리해석하였다. 지반의 강성 및 감쇠특성을 적절히 고려할 수 있는 주파수영역기법에 대하여 주로 연구하였으며, 시간영역해석에서는 지반-구조계의 첫번째 고유진동수에 해당하는 지반의 동적강성을 사용하여 주파수에 독립적인 강성과 감쇠를 결정하였고, Gauss-Seidel 반복법을 사용하여 지반의 감쇠특성에 기인한 비비례 감쇠항을 고려할 수 있도록 하였다. 예제해석은 층상지반을 통과하는 지하철 인근에 위치한 구조물에 대해 수행하였다.Dynamic analysis methods for building structures under subway transit loadings using the methods which includes soil-structure interaction effect in frequency and time domains are studied. An effcient substructure interaction effect in frequency and time domains are studied. An effcient substructure method is proposed using the dynamic stiffness matrix which have been evaluated by the direct method and equivalent transit loading along the soil-structure interface. The dynamic stiffness of soil is evaluated by effect. In time domain anlaysis, frequency-independent stiffness and damping of soil are determined at a representative frequency. A mode superposition method equipped with the Gauss-Seidel iteration technique is employed. Example analysis is carried out for a building structure embedded into a layered soil medium. | en |

dc.description.alternativeAbstract | Dynamic analysis methods for building structures under subway transit loadings using the methods which includes soil-structure method is proposed using the dynamic stiffness matrix which have been evaluated by the direct method and equivalent transit loading along the soil-structure interface. The dynamic stiffness of soil is evaluated by the finite element method incorporating infinite elements for the radiational damping effect. In time domain analysis, frequency-independent stiffness and damping of soil are determined at a representative frequency. A mode superposition method equipped with the Gauss-Serdel iteration technique is employed. Example analysis is carried out for a building structure embedded into a layered soil medium. | en |
