BOND OF RIBBED BARS UNDER HIGH CYCLE REPEATED LOADS

To determine the bond behavior of ribbed bars under repeated loads, 308 pullout specimens were tested. The specimens failed by pulling out of the bars. In the tests the following parameters were varied: maximum load and load amplitude, bar diameter, concrete quality, and bond length. Furthermore, as a comparison, tests under sustained load were carried out. A repeated load has a similar influence on the bond as on the deformation and failure behavior of unreinforced conrete, and it accelerates, in comparision with a sustained load, the nonelastic deformation (slip). /Author/
