Abstract: This paper presents results of monotonic and cyclic tests with post-installed reinforcing bars performed at the research laboratory of the University Stuttgart. The main objective was to study the behavior of post-installed rebar connections in uncracked concrete under cyclic loading. Varied was the type of mortar and the peak displacements during reversed cyclic loading between constant displacements.
The results show that the behavior of post-installed rebars under cyclic loading depends on the failure mode under monotonic loading. If pullout is caused by a bond failure between mortar and bar, the cyclic behavior of post-installed rebars is much the same as for cast-in-place rebars. On the contrary if pullout is caused by a bond failure between mortar and concrete then the bond behavior of post-installed rebars under reversed cyclic excitations maybe rather poor. In the paper the tests and the evaluation of the results are presented.
