Abstract: Experimental pull-out test and finite element analysis (FEM) are conducted in order to discuss the pull-out behaviour of post-installed adhesive anchor filled with ultra-high performance fibre reinforced concrete (UHPFRC) as an adhesive. The numerical results by the FEM revealed that the constitutive laws of interface elements between the substrate concrete and the adhesive significantly affect the peak load and the deformation of post-installed adhesive anchor under the pull-out force. It suggests the significance of the mechanical properties of the interface, i.e., the surface treatment of the hole for the anchor in the substrate concrete. Furthermore, analytical results were consistent to the experimental crack pattern of mixed bond-cone failure of the adhesive anchor. The development process of the crack pattern is also analysed step by step, which shows a mechanism derived from the uniform development of shear stress along the depth of the anchor due to the high modulus of the adhesive UHPFRC.
