摘要：
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.
