Abstract

In this study, it was conducted to improve the performance of stud of Steel Plate Concrete(SC) walls subjected to bending moment. Non-linearity of contact interface, connection, and material properties were considered in finite element modeling of SC wall. In order to validate the analytical model, furthermore, a foregoing laboratory experiment was simulated by FEM, so that comparison between the measured result and the analysis result have be done. The size of the analytical model was determined by reflecting various references and the analyses were performed according to various shapes and arrangements of stud. Additionally, the validity of the model considering the related provisions in the KEPIC SNG standard was also considered. As a result, the optimal shape and spacing of studs was proposed through this numerical analysis and standard verification.

본 연구에서는 휨모멘트를 받는 SC 벽체 스터드의 성능을 최적화시키기 위해 비선형 유한요소법을 사용한 해석적 연구를 수행하였다. SC 벽체에 대한 유한요소모형에서는 접촉, 연결, 그리고 재료에 대한 비선형성을 고려하였다. 그리고 해석모형의 검증을 위해 선행된 실내 실험을 모사하여 계측결과와 해석결과를 비교하였고, 제안된 해석방법의 타당성을 검증하였다. 문헌조사를 통해 해석 대상물의 크기를 결정하였고, 다양한 스터드의 형식과 배치간격을 고려한 해석을 수행하였다. 또한, KEPIC SNG를 만족하는지에 대한 추가적인 검토를 수행하였다. 최종적으로 수치해석과 기준의 검토를 통하여 개선된 스터드의 최적 형식 및 배치안을 제시하였다.
