The purpose of this study is to reveal the wood joinery technique in the ancient era. Joinery is one of the core techniques in constructing timber frame architecture in the Korean peninsula. These techniques can be revealed by examining wooden members of ancient buildings. The members were excavated at the Donggung Palace and Wolji Pond, the historic site in Gyeongju. This study collects the data of 284 members excavated at the Donggung Palace and Wolji Pond and analyzes the details such as length, thickness, width, joint types, joint shapes. With the result of the analysis, this study tries to indicate the level of wood joinery techniques in ancient buildings.

본 연구에서는 휨을 받는 압축강도 80 MPa 수준의 고강도 콘크리트 부재의 구조거동 실험 연구를 수행하였다. 실험변수는 보통(SD 400) 및 고강도(SD 600)철근, 0.98~1.58%의 종방향 철근비, 200×250, 200×300 mm의 단면크기를 고려하였다. 9개의 보 부재를 제작하여 휨 실 험을 수행하였으며 극한휨강도, 하중-처짐 관계, 균열 형태, 파괴형상 및 연성을 파악하였다. 실험결과는 철근비가 증가함에 따라 휨강도는 증 가하고 연성은 감소한다. 또한, 철근비가 증가함에 따라 균열의 개수가 증가하며 균열폭은 감소하는 경향을 나타내었다. 철근의 강도 등급에 따른 하중-균열폭 관계는 뚜렷한 차이를 나타내지 않는다. 콘크리트 비선형거동 해석을 수행하였으며, 극한하중 예측값과 측정값을 비교하였 다. 고강도 콘크리트의 휨거동 예측 결과는 실험부재의 휨강도를 전반적으로 과소평가하고 있다.

The purpose of this study is to evaluate a RCS strengthening method for medium & low-rise R/C buildings using the nonlinear analyses of member levels. In this study, a three-story R/C buildings that represents a typical Korean school building constructed in the 1980s was selected. Seismic capacities of the building before and after strengthening with the RCS method are evaluated using the nonlinear static & dynamic analyses of member levels.

The purpose of this paper is to verify the seismic strengthening effect of R/C buildings strengthened with the Carbon Fiber Composite Cable (CFCC) In this study, a three-story R/C building that constructed in the 1980s was selected, and its seismic performance before and after strengthening was evaluated based on the nonlinear dynamic analyses of members levels. The result indicated that the seismic strengthening effect of the proposed CFCC method was verified in terms of both strength and ductility demands, compared to the building before strengthening.
