An Experimental Study on Effect Factors of Post-Installed Bar in Concrete Anchorage and Bonding Performance
The bonding properties of post-installed bar in concrete are fundamental to evaluate the results of reinforced concrete. Including 102 specimen of post-installed bar and 18 specimen of embedded bar, 120 specimens were tested by pull-out test altogether. Comparative analysis considering diameter of steel bar, tensile strength of concrete, anchoring depth of steel bar, anchorage aperture are conducted. Based on the experimental results, it is shown that the bonding properties of post-installed bar are significantly influenced by steel bar, concrete tensile strength, installed depth bar and anchorage aperture. The ultimate average pullout forces of steels in specimen of post-installed bar and specimen of embedded bar are nearly equal. Three kinds of failure models are obtained. The experimental results can be useful for analyzing and evaluating bonding behaviors of post-installed bar in concrete.
