본 연구의 목적은 소성영역에서의 철골 부재내에 존재하는 존재응력을 추정하는 법을 개발하기 위함이다. 여기에선 선행 실험 연구를 근거로 하여 응력집중 현상에 기인한 국부 소성화를 고려하여 보정계수법이 제안되었다. 구멍주위의 응력 분포를 파악하기 위하여 유한요소 해석을 수행하였고, 그 결과를 탄 소성역에서의 구멍내기법에 의한 결과와 비교하였다. 보정계수법을 적용한 결과, 본 연구에서 제안된 방법은 실재 초기 존재응력값과 약 2% 정도의 오차를 가진 매우 좋은 결과치를 나타냈다. The purpose of this study is to develop a method to deduce existing stress of steel member in inelastic range. Based on the previous experimental study, modified factor method considering the local plastification due to stress concentration was proposed. Finite element analysis was performed to investigate the stress distribution around hole and the results of the finite element analysis were compared with those from the Hole Drilling Method in elastic-plastic range. As a result of applying a modified factor method, proposed method shows very good approximation of 2% error for exact value of stress in the plastic range.

In this study, we performed a series of experimental studies on the effect of tie-bars and steel-plate strength on the impact resistance of SC walls. A total of 8 impact tests were planned to investigate the impact resistance performance of SC walls at the extreme performance testing center of Seoul National University in Korea. The specimens were designed with the main test parameters of yield strength of steel plate and tie-bars. The results from this study will be used to improve and optimize the AISC N690 design equation for SC walls.

In recent days, SC(Steel plate concrete) structure has been widely used in the design of the nuclear power structure because of its construction efficiency. However, the structural characteristics of RC(Reinforced concrete)-SC(Steel plate concrete) wall connection are not yet studied sufficiently and not clarified completely. In this study, an experimental study to investigate the structural behavior of the RC-SC Wall I Type Connection was carried out. The maximum in-plane shear strength and failure mode were examined, and the results were also compared with theoretical value. Finally, the results plan to be used for the basic reference of the design guideline(draft) for the RC-SC wall connection.

Seismic capacity evaluation of Fossile power plant facilities must be carried out with appropriate evaluation scopes and methods according to guidelines and philosophies. But currently, there is no accurate seismic capacity evaluation provision of existing turbine generator structure in Fossil power plant. The purpose of this study is to evaluate accurate nonlinear seismic capacity of turbine generator structure. Seismic evaluation procedure is performed based on Capacity spectrum method(ATC-40). Nonlinear static analysis was performed and performance point for each seismic load level was computed. From the rusults, Although the turbine structure was designed for Z=0.075, it was sufficient to Z=0.15, 0.4’s earthquake demand.

This paper presents the current status of development of assessment program for shock/Fire damage caused by aircraft impacts for NPP(nuclear power plants). According to international and domestic regulations, the design of nuclear power plants have to take into account the potential effects of the impact of a large commercial aircraft. In this study, we set up the practical application procedure to assess the shock/fire damage due to aircraft impacts for NPP in accordance with NEI(Nuclear Energy Institute)07-13 rule set and are developing the aircraft impact assessment program to reduce the effort and improve the accuracy.
