Strength and structural barrier function of steel channel-reinforced concrete composite slabs

Abstract     [Full Text]
    This paper reports on the development of a new composite slab system that uses a large- lipped steel channel and reinforced concrete. The advantages of this new system are that it serves as both a structural unit and an unsupported form and it has a secondary structural barrier function. A concrete pouring test wasrncarried out for the large-lipped steel channel. Full-scale tests were carried out to assess the flexural strengthdeformation characteristics and structural mechanics of the composite slab. The barrier mechanics of the steel channel concrete element (referred to as the SC subunit) of the composite slab are examined. The test resultsrnindicate that the new composite slab has excellent strength, ductility haracteristics, and a structural barrier function in its SC subunit that is highly effective against severe loading.
 
Key Words
