Abstract

According to the results of pullout-test for adhesive steel bar in concrete, a bond-slip relationship on adhesive interface is established. This relationship reflects effect of some parameters, such as effective embedment length, drill diameter, characters of anchor adhesive, etc., on bonding strength and slip of mixed interface. The finite element method was used for the analysis of adhesive anchorage system. The pull out loading process was simulated and a complete tension-displacement curve of the steel bar was obtained by finite element analysis. The distribution of stress and the development of cracks in concrete can be described in detail according to numerical computation. The analytical results coincide with the experimental results which proved that the analysis model is effective and the parameters are reliable. Through a large number of numerical calculations on adhesive anchorage system, the basic laws of stress distribution in steel bar, adhesive glue and concrete are obtained for different embedment length. The model provides the analytical tools and basic method for the analysis of adhesive anchorage system in micro-level.
