“…All the concrete blocks and anchor bolts are 0.1 m thick, which is very small as compared to other dimensions, so the model is treated as a plane stress problem in the analysis. In most of the past research works 6 Mathematical Problems in Engineering [9,10,14], steel bolt was also not directly modeled and there were no experimental values of friction coefficients. Pullout load is modeled by controlling the vertical displacement of the top surface of the bolt head and for the convenience of simulations only the anchor head is assumed to be in contact with the concrete.…”

“…Recent developments of mesh-free (or meshless) methods such as diffuse element method (DEM), material point method (MPM), and element free Galerkin method (EFGM) are invented to circumvent the mesh-dependence problem and relieve the volumetric locking for suitable choice of support size of shape function [15,16]. Soparat and Nanakorn [14] and Coetzee et al [17] used mesh-free methods for pullout problems. Though many discussions on the advantages of the mesh-free methods have been reported [15][16][17][18], it should still be noted that the treatment of essential boundary conditions is not straightforward as the conventional FEM and the use of shape functions of any desired order of continuity may lead to computational difficulties and complexity in deriving the coefficients of the stiffness matrix [18,19].…”

Predictive simulation of anchor pullout from concrete structures is not only a serious problem in structural mechanics but also very important in structural design safety. In the finite element method (FEM), the crack paths or the points of crack initiation usually need to be assumed in advance. Otherwise, some special crack growth treatment or adaptive remeshing algorithm is normally used. In this paper, an extended peridynamic method was introduced to avoid the difficulties found in FEM, and its application on anchor bolt pullout in plain concrete is studied. In the analysis, the interaction between the anchor bolt and concrete is represented by a modified short-range force and an extended bond-level model for concrete is developed. Numerical analysis results indicate that the peak pullout load obtained and the crack branching of the anchoring system agreed well with the experimental investigations.

“…(Hariyadi, Munemoto and Sonoda, 2017) The pull out strength of anchor bolts embedded in concrete is primarily determined by both the tensile strength of the concrete embedded therein, and the strength of the bond formed between the chosen resin and surrounding concrete.

Anchor bolts are often fixed into a concrete soffit of structures and they are used in ambient and cold store locations. The chemical anchor bolt relies purely on the tensile strength of the concrete to carry the imposed load, assuming the bond strength of the resin is greater than the tensile strength of the concrete. The properties of concrete are changed by the addition of both steel and polypropylene fibres. This paper investigates the relative performance of each fibre type with regard to initial and final post crack failure. Anchor bolt pull-out testing was used to determine the maximum load a fixing can hold as well as the residual post crack toughness of a bolt embedded in a concrete block. The concrete used was a C40 design mix and resin anchor bolts were selected for this test for their stress-free conditions prior to loading. The results showed that the addition of both types of fibres when used in concrete improved the maximum load and toughness of the samples, compared to plain concrete. There was not a significant difference between the results obtained for steel and polypropylene fibres. The effects of a reduction in core temperature of the samples was examined. The results show that the strength of concrete is significantly improved when tested at-20°C, compared to ambient temperature.
