Push out Test, Shear Connectors, Reactive Powder Concrete, High Strength Concrete 


Özet

The push-out sample consists of a small part of steel column. It is linked to a concrete wall through its both sides by connectors resisting shear force. The slip between the wall and the steel is measured at changing load increments or displacements. In this thesis, the structural behavior of three different types of shear connectors (Headed stud, L-shaped, and Channel) with ordinary and high strength steel properties embedded in different types of concrete (ordinary concrete, high strength concrete, and reactive powder concrete) was studied. The objective of this study was to investigate the behavior of selected shear connectors to determine the mechanical properties of different types of concrete and study the shear stiffness of shear connectors by conducting a total of 36 push-out tests specimens. In these test specimens, three types of shear connectors, headed stud, L – shaped and channel types of connectors, with two types of bond, welded and epoxy, were used. The results of this study indicated that reactive powder concrete increased mechanical properties of concrete as the concrete age increased. The specimens, OCHW, HCHW and RCHW generated the best shear force values for normal weight, high strength, and reactive powder concrete, respectively (The first letter is used to define the type of concrete: “O” is for ordinary, “H” is for high strength and “R” is for reactive powder concrete. The second letter is used to describe the type of shear connector, “C” is for channel connecter. The third letter is used to define the steel type for shear connector, “H” is for high strength steel. The fourth and the last one is used for the type of connections between the studs and the steel plate, “W” is for Welding).
