내진상세를 가진 2경간 2층 모멘트 저항 철근콘크리트 평면구조물을 설계하고 상사법칙에 근거하여 1/2.5 크기의 구조물과 1/10 축소모델을 제작하였다. 다음, 이 구조물에 변위 조절하에서 반복횡하중 실험을 실시하였다. 이들 실험결과에 근거하여 강도, 강성, 에너지 소산능력, 파괴모드, 국부변형등과 같은 구조적 거동 특성을 상사성의 관점에서 비교하였다. 이 결과를 근거로 하여 다음과 같은 결론을 얻었다. ; (1)1/10 축소모델에서의 강도는 1/2.5구조물의 강도와 매우 유사하였다. (2)1/10축소모델의 초기 강성은 대략 1/2.5구조물의 초기 강성의 2/3 정도로 나타났다. (3)1/10축소모델은 1/2.5 구조물 보다 더 작은 에너지 소산능력을 나타내었다. (4) 1/2.5구조물과 1/10축소모델의 비탄성 붕괴 메카니즘이 약간의 차이를 나타내고 있다. The objective of this study is to investigate the characteristics of elastic and inelastic bekavior of ductile momenting-resisting reinforced concrete frame subjected to reversed lateral loading such as earthquake excitations. For this purpose, a 2-bay 2-story reinforced concrete plane frame with seismic detail was designed and one 1/2.5-scale subassemblage was manufactured according to the required similitude law. Then, the reversed load test under the displacement control was performed statically to this subassemblage. Finally, the results of this test were analysed regarding to (1) the design load vs actual strength, (2) degradation in stiffness and strength. (3) failure mode or energy dissipation. (4) local deformations.

Life styles of occupants may change during whole life of an apartment as the lifetime of the building gets longer. Therefore, spatial flexibility in apartments becomes more important. New structural systems and architectural plans should be developed to meet requirements of spatial flexibility. The Ministry of Construction and Transportation (MOCT) recently stipulated several special regulations regarding spatial flexibility and encouraged a flat plate system instead of a shear wall system by providing incentive for the upper limit of prices and floor space indices of apartments. In this paper, a flat plate system with edge beams is developed to replace a shear wall system for conventional apartments. A shear wall system has been optimized for apartments in Korea. The applicability and the construction cost of a new developed structural system with advanced spatial flexibility should be investigated compared with the shear wall system. To assess the construction cost and the applicability of the flat plate system, total 24 buildings are designed and the costs are evaluated. Two types of plans (tower and rectangular) and two kinds of space (110m2 and 140m2) are selected. The buildings have three kinds of stories, 15, 25 and 35 (30 stories for rectangular type). Buildings with a flat plate system are designed to have similar structural performance to buildings with a shear wall system. The total costs of structural frames and dry walls for partitions are evaluated for the proposed flat plate system with varying stories, types, and size of houses. The results of this research can be used in determining feasibility of residential projects.
