Study of the Behavior of Shear Connectors in Composite Structures Using FEM

الملخص

Composite structures consisting of concrete slab and rolled up steel sections are widely used structural members in bridges and high rise buildings. The composite action is established by connecting the concrete slab and the steel section by using shear connectors.

Shear Connectors are used to enhance proper connection and resist horizontal shear forces. A Composite member has to be designed in such a way that before composite structural element reaches ultimate capacity, shear connectors should not fail due to lack of ductility.

In this study, Finite Element Analysis had been carried out for four types of shear connectors for ductility criteria. Push-out test Specimen and Composite beam modeling with four different types of shear connectors was done by ANSYS and were analyzed. The Analytical results are presented and focused on the study of ductility behavior and load slip behavior of different types of connectors in composite beams according to EURO Code 4. The best connector for a particular composite beam has been evaluated based on its performance under static load keeping the loading. It was concluded that the I-type and channel-type are ductile connectors with larger shear ultimate capacity comparing with plate and stud types that were not ductile connectors.
