Abstract

This paper presents the results of push-out test conducted for the perfobond rib shear connectors welded onto steel-concrete composite deck. Push-out test specimen consists of profiled steel sheeting, perfobond rib, reinforcement, and concrete. To provide longitudinal shear resistance between the profiled sheeting and the concrete, perfobond rib with a number of holes was used. The parameters considered in the design of perfobond rib were the spacing and location of holes, and effect of reinforcing bars placed in the holes. To validate the effectiveness of the proposed system, twelve specimens were fabricated and tested. Although the scope of test was limited in nature, the results of test have shown that the perfobond ribs can be effectively used for shear connection in the steel-concrete composite decks.

본 연구에서는 강-콘크리트 합성 바닥판용 유공판재형 전단연결재의 전단성능을 평가하기 위한 전단실험을 수행하고 그 실험결과를 고찰하였다. 전단 실험체는 절곡된 강판, 유공판재형 전단연결재, 철근, 콘크리트로 구성되었으며, 절곡된 강판과 콘크리트 사이에 작용하는 수평전단력에 저항할 수 있도록 다수의 구멍이 가공된 유공판재형 전단연결재가 적용되었다. 실험체설계에 적용된 변수는 구멍의 간격과 위치, 구멍관통 철근의 유무이며, 총 12개의 실험체를 제작하여 전단실험을 수행하였다. 제한적 범위 내에서 수행한 실험결과에 따르면 유공판재형 전단연결재가 강-콘크리트 합성 바닥판에 효과적으로 사용될 수 있을 것으로 판단된다.
