For new construction, recently, it has expended from physical performance standard to completed apartment' blemish warranty and countermeasure strategy contents. And considering element technology is increasing remodeling’ easiness for deciding operation right or wrong the aged apartment’ re-construction or remodeling. In addition, international standardization of building performance makes rapid progress the point of ISO. In Japan, study of housing commission will be done on a national level for the long commission metropolitan gathering house construction and reproduction technical development, and, already, involving study of approval system of building element made progress. It set the goal performance log index of remodeling’ easiness, it set up component element between a part and public standard type in remodeling. In plan and design phase, it is a precondition that make the performance on the basis of user demand in the whole of Use, maintenance, repair, waste and reuse. Therefore, in the building technology case that development of element technology and practical use are fast in progress, a user is required to evaluate/choice according to performance. And a developer is required to the technical development that aim performance is cleared. The study selected a detailed item about performance item of re-modeling element technique through the requirement which the nations (such as America, England, Japan, etc) and the agencies of foreign countries present and item selection standard, from the point of view where the interest not only the individual but also govemmental politic viewpoint is coming to be higher re-modelling than new construction.
Before incorporating the earthquake-resistance design in design code(1988), most of existing residential buildings were built without having lateral resistance capacity in addition to their structural peculiarity such as exterior stair ways, exterior elevator room. For these reasons, the retrofitting research demands for existing buildings arise recently and many retrofitting methods are proposed. These tasks are irnportant to reduce the enormous economic loss and environmental issues. The objective of this study is to predict the perforrnance increase due to various strengthen schemes and suggest adequate strengthen methods for wall type apartment buildings not designed to resist earthquake.

For these reasons, the retrofitting research demands for existing buildings arise recently and many retrofitting methods are proposed. These tasks are important to reduce the enormous economic loss and environmental issues. In this study, Scaled residential buildings with/without lateral resistance were tested and monitored with external lateral load especially toward the longer side of the building. From these experiments, enhanced retrofitting methods of old shear wall system are proposed and also compared with structural analysis.
공동주택 리모델링 공사에서 필연적으로 발생하는 신/구 구조체의 접합에 사용되는 부착식 후시공 앵커에 대한 시공성 및 인장성능을 확인하기 위하여 30년 이상 경과된 노후 공동주택의 기초판에서 부착식 후시공 앵커에 대한 인발실험을 수행하였다. 후시공 앵커는 리모델링 설계에 주로 사용되는 SD500 이형철근으로 3종류의 직경과 매입깊이를 변수로 직접 인발성능을 검증하였다. 부착식 후시공 앵커의 현장 인발실험결과, 모든 철근직경에서 현행 기준에서 제시하는 부착식 앵커의 설계 묻힘깊이 이하에서 철근 인장파괴가 발생하였다.
