Comparative analysis between the shear resistance of the Truss Type shear connector and stud bolt

Resumo

Shear connectors are extremely important in the functioning of composite steel-concrete structures, as
they are responsible for carrying out the transmission of forces between the steel beam and the concrete slab. The
Truss Type shear connector is an alternative connector that aligns efficient structural behavior, agility of execution
and low cost of production when compared to conventional shear connectors (stud bolt, for example) applied in
composite structures. However, due to the short time of existence, there is still a lack regarding the understanding
of the mechanical behavior of the Truss Type connector. Thus, this study aims to perform a comparative analysis
between the shear resistance of the Truss Type connector and stud bolt. This study was conducted from the
development of a non-linear three-dimensional finite element numerical model for simulating push-out tests with
Truss Type connector. The results showed that the Truss Type connector has a strong capacity and a higher
load/cross section ratio than stud bolt, even when manufactured with materials with identical properties.
