초록

현재 강재교각 기초부의 설계에 적용되어지고 있는 형식은 기초 콘크리트 내부에 앵커프레임을 설치하여 교각부와 연결하는 형태로 설계 및 시공을 하고 있다. 이는 복잡한 설계와 시공으로 인하여 기초부의 크기가 커지고, 과대 설계되는 경향이 있다. 본 연구에서는 고성능강을 이용한 교각 기초부의 연결상세와 관련하여 새로운 형상을 제안하기 위하여 기존 설계기준에 의한 시험체와 고장력 앵커를 사용한 새로운 연결형상 시험체 등 총 3개의 시험체를 제작하여 실내 시험을 실시하였다. 이를 통하여 각 시험체의 성능을 비교·분석하여 연결형식에 따른 구조물의 거동특성을 분석하였다.

Abstract

Generally, a steel pier-foundation has been designed and constructed with a anchor frame. However, because of the complicated design and construction, the foundation’s size has become large and has been overdesigned. In this study, three specimens were made and the tests were conducted to suggest a new shape in regard to the pier- foundation’s joint details using the high performance steel. One of the specimens was made up of the general anchors and the anchor frame. Another specimen consisted of the high tension anchors and the studs, and the other specimen was composed of the high tension anchors and the inner steels. After the performance of each specimen was compared and analyzed, the behavior characteristics according to the joint were analyzed.
