Abstract :
The steel-concrete hybrid structural elements rely on the transfer of force between the two materials in order to realize the benefits of hybrid action. And the problems in design are related to the problem of force transmission between concrete and embedded steel profiles. So it creates a situation in which it is not known how to combine the resistances provided by stud and plate connectors, and how to reinforce the concrete in the transition zone. This study covers the design and analysis of some hybrid specimen for push-off test to transfer forces from the steel profile to the concrete wall and gives an idea about behavior of various connectors. Rigid connectors like plate bearing shows relatively more resistance by creating struts and tie effects inside concrete where flexible connectors allows more slip. And it is not a good idea to use both type of connector together because of their unlike load-slip behavior.
