A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedded in high strength concrete is insufficient until today. So it is necessary to evaluate the load-slip behavior and the shear capacity of studs embedded in high strength concrete for the appropriate design code. In this paper, it was performed push-out tests of shear studs embedded in high strength concrete and fiber reinforced concrete used widely in high-rise building. Experimental push-out tests were used to evaluate both the shear stud capacity and the load-slip curve of the connector. And the results of the finite element model are compared with push-out tests and the values given in current codes of practice.

A lot of push-out test results of studs in normal strength concrete have been presented. So present design methods in the codes for the calculation of the shear strength of studs are based on the test results of studs embedded in normal strength concrete. But knowledge of the load-slip behavior and the shear capacity of the stud in high strength concrete are limited to data obtained from the experimental push-off tests. So It is necessirary to evaluate the shear capacity of studs embedded in high strength concrete for the appropriate design code. Because it shows that the concrete compressive strength significantly affects the strength of the stud connections. In this paper, it was performed push-out test of shear studs in high strength concrete used in construction of high-rise building. Test results are compared with them calculated from current design codes.
