Abstract

Recently, the use of transfer slab system has increased greatly. However, several construction problems are being encountered owing to its excessive thickness. Therefore, in this study, a transfer slab system that uses a reverse drop panel, which can utilize the facility space of the pit floor by reducing the transfer slab thickness, was considered. To investigate the shear behavior of transfer slab system that uses the reverse drop panel, the two-way shear strength of transfer slab-column connection with the reverse drop panel was analyzed using nonlinear FE analysis. In addition, the two-way shear strength evaluations of transfer slab with the reverse drop panel conducted using the existing evaluation methods were verified by comparing the strengths predicted by those methods with the results of nonlinear FE analysis.

최근 건축구조물에서 전이슬래브 시스템의 사용이 증가하고 있다. 하지만 과도한 전이슬래브의 두께로 인한 경제적, 시공적인 문제가 많이 발생하고 있다. 따라서, 본 연구에서는 피트층의 설비 공간을 활용하여 전이슬래브의 두께를 절감하기 위하여 역드랍 패널을 적용한 전이슬래브 시스템을 고려하였다. 역드랍 패널을 사용하여 전이슬래브의 2면 전단강도를 증진시킴으로써 전이슬래브의 두께를 줄이고자 하였다. 따라서, 역드랍 패널을 이용한 전이슬래브 시스템의 유효성을 검증하고 전단거동을 조사하기 위하여 다양한 설계변수에 대한 역드랍 패널을 적용한 전이슬래브-기둥 접합부의 전단거동을 기존연구에서 검증된 비선형 FEM 해석방법을 사용하여 분석하였다. 최종적으로 비선형 FEM 해석결과와 기존의 2면 전단강도 평가식으로 예측한 전단강도를 비교·분석하여 기존 평가식의 역드랍 패널을 적용한 전이슬래브-기둥 접합부의 2면 전단강도 평가에 대한 유효성을 검증하였다.
