Abstract

Highlights: Experimental and numerical tests of new connector, the Truss Type shear connector. Truss-Type connector (TT-connector) cross section area is equivalent to 19 mm stud-bolt. In push out-out tests, TT-connector showed more resistance than the 19 mm stud bolt. The tests showed TT-connector has good ductility and stress distribution. TT-connector may be used when the equipment for stud-bolt application is unavailable. Abstract: Shear connectors are important in composite steel-concrete beams. This work presents a new connector, named truss-type shear connector. This connector is an alternative to replace stud bolt in special situation. The connector's geometry was conceived aiming at low cost, easy execution, high resistance, and efficiency concerning slipping and uplift. Six specimens were constructed for push-out tests comparing this alternative connector with stud bolts. The behavior of the specimens was investigated for collapse, slipping and uplift. Experimental results were compared against numerical FE simulation showing good agreement and providing a global view of the truss-type shear connector behavior and its viability.
