ABSTRACT:

This paper aims to present theoretical and experimental results of composite joists with partially encased steel beam under static and cyclic loading. The joist structural behaviour is improved by the composite action between both materials. The shear transfer mechanism is established through an innovative shear connection by adhesive bonding, friction and dowel action of transversal reinforcing bars passing through web holes. A full-scale composite beam was tested to gather information on its flexural response and to assess the shear resistance mechanism. Before the ultimate loading test, the beam was subject to cyclic loading and did not present significant damage signs after seven thousand cycles. The results of the statically loaded test showed a rigid connection produced by the adhesion and friction of the embedded profile in the concrete slab, and the capability of the composite beam to develop its plastic bending moment capacity.
