Prospective study on the behaviour of composite beams with an indented shear connector

The experimental tests and the numerical models were developed to evaluate the behaviour of the composite beam and particularly the indented shear connector in analysis. The tested specimens consist on a steel beam with a continuous indented connector, positioned on the upper flange of the beam and continuously welded in its development, and a reinforced concrete slab, in a total span of 3000 mm. During the tests, the connector provided high stiffness and a full interaction between the concrete slab and the steel beam. The beams failure was determined by crushing on the upper part of the concrete slab.
