Tests on Composite Beams with Low Levels of Shear Connection

The paper describes an experimental investigation into the behaviour of four full-scale composite beams. Each beam comprised a slab, cast using profiled steel decking, acting with a steel universal beam section. The connection between slab and beam was made using stud shear connectors welded through the profiled steel sheeting. Relatively few connectors were used as the main aim of the investigation was to study the behaviour of such beams with shear connection levels of less than 50 % of that required to ensure full shear connection. A secondary aim of the work was to investigate whether or not the web-cleated end connections acted as pinned supports as assumed in the design. Comparisons between roller supports and web-cleated connections were therfore made during testing. Measurements of the natural frequency of the beams were also made. H.D. Wright and R.W. Francis
