초록

본 연구에서는 구조단열패널을 구조 벽체로서 활용하기 위하여 개구부를 설치한 후 편심축하중 실험 및 해석을 수행 하였다. 실험체의 크기는 1200×2400㎜이다. 실험체는 7개로서 개구부의 크기와 개구부 보강방법, 강재를 시용한 구조단열패널 보강을 변수로 하여 진행하였다. 구조단열패널에 대하여 개구부 설치에 따른 구조적 거동을 분석하기 위한 변수해석을 수행하였다. 구조성능 실험 결과와의 비교분석을 통해 해석에 대한 검증을 하였고, 개구부 크기를 변수로 하여 편심축하중을 받는 구조단열패널의 구조적 거동을 유한요소해석을 통하여 분석하였다. 이를 통해 구조단열패널에 적합한 최적의 개구부 형상을 제안 하고자 한다.

Eccentric axial load tests were carried out to get the structural performance of the SIP (Structural Insulated Panels), which is widely used as residential type in Europe and North America. Outside the country, design standards for SIP have been prepared and related research has been carried out variously. However, in Korea, the research on the performance of the structural insulated panels is very small, and the related standard is not provided. In this study, the eccentric axial load was applied after the opening was installed to utilize the structural insulated panels as the structural wall. The size of the test specimen is 1200×2400㎜. The number of test specimens was 7, and the size of the openings and the reinforcement method around the openings were used as variables. Variable analysis was carried out to suggest the optimal opening dimension. The analytical model was verified through comparison with experimental results and the structural behavior of the structural adiabatic panel subjected to eccentric axial load with the opening size as a parameter was analyzed through finite element analysis. Through this, we propose an optimal opening size suitable for the structural insulated panels.
