Shear studs are commonly used to transfer longitudinal shear forces across steel-concrete interface in composite member design. A lot of push-out tests of shear studs embedded in normal and high strength concrete were conducted. But there is not study of shear stud considered resistance of horizontal load and bearing strength of concrete until now. In this paper, it was performed push-out tests of large double head shear stud embedded in high strength concrete.(double head stud means that head of stud was installed on the above and the lower part.) and the strength of shear stud was evaluated with bearing strength of concrete and resistance of horizontal load between concrete slabs. Experimental push-out tests were compared with theoretical calculation results.
