| Abstract |
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. |
