- W4243483975 abstract "상부벽식-하부골조 구조(복합구조)는 일반적으로 전이층을 중심으로 상부는 주거공간의 전단벽식의 고층아파트이고 하부는 상업공간의 보-기등의 골조구조이다. 이러한 구조물은 구조형식의 특성상 강성비정형, 질량비정형, 기하학적 비정형 등 비정형 형태의 특징을 갖고 있다. 본 연구에서는 하부골조 구조물의 층수가 변화할 경우에 대해 복합 구조물의 비선형 거동특성과 내진성능을 파악하였다. 비선형 해석결과로부터 얻은 결론은 다음과 같다. 1) 비선형 정적해석의 최상층변위각과 밑면전 단력계수로부터 하부구조의 층수가 증가할 경우 구조물의 밑면전단력계수는 감소하였으나 최상층변위각은 증가하였다. 2) 하부구조의 층수가 증가할 경우 상부벽식구조의 층간변위각과 소성율은 감소하였으며, 상부벽식은 탄성상태에 가까운 거동을 하였다. 3) 하부구조의 층수가 증가할 경우 하부구조에서 층간변위각이 집중적으로 증가하였다. The upper wall-lower frame structures(mixed building structures) are usually composed of shear wall structure in the upper part of structure which is used as residential space and frame structure in the lower part of structure which is used as commercial space centering around the transfer system in the lower part of structure. These structures are characteristics of stiffness irregularity, mass irregularity, and vertical geometric irregularity. The purpose of this study is to investigate the nonlinear response characteristics and the seismic capacity of mixed building structures when the number of stories in the lower frame is varied. The conclusions of this study are following. 1) As the result of push-over analysis of structure such as roof drift(i.e. roof displacement/structural height) and base shear coefficient, when the stories of lower frame system are increased, base shear coefficient is decreased, but roof drift is increased. 2) According to an increase in stories of the lower fame, story drift and ductility ratio of upper wall system are decreased and behavior of upper wall system is closed to elastic. 3) When the stories of lower frame system are increased, the excessive story drift is concentrated on the lower frame system." @default.
