Özet

Push-out tests are used to determine shear connectors’ properties where two smallreinforced concrete walls are attached to the top and bottom flanges of an I-sectionthrough four shear studs located on both its flanges. In this study, the structural behavior of shear connectors was examined by testing a total of 36 push-out specimens.In these specimens, various test parameters were used. The types of shear connectors and their strengths, their connection types, and the strength of the concrete inwhich they were embedded were all investigated. Headed, L-shaped, and C-shapedstuds were selected in this experimental study to represent different types of shearconnectors. These shear connectors were assumed to be either ordinary or highstrength steel-embedded in three different types of concrete: ordinary, high strength,and reactive powder concretes. In these tests, the shear connectors were connectedthrough welding or epoxy bonding. The objective of this study was to investigate thestructural behaviors of these different types of shear connectors by focusing on theirshear force capacities and slip values. The test results indicate that the reactive powder concrete increased the mechanical properties of concrete as the concrete age increased. The specimens with C-shaped studs made of high-strength steel with weldedstuds embedded in normal weight, high strength and reactive powder concretes, generated the maximum shear resistance values.
