3 Yijun Li, Sandeep Patil, Bernhard Winkle and Tobias Neumaier 3 SIMULATION SET-UP The simulation set-up for a pullout test of a screw anchor in concrete is shown in Figure 4. developed by Hilti Corporation. A typical finite element mode for the simulation is shown in Figure 5. Figure 5: FE mode of concrete screw. Figure 4: Simulation set-up of a concrete screw. The tensile load is applied at the head of screw. The resistance boundary conditions are applied on the top surface of the concrete block. The distance between the applied boundary and the anchor center is larger than 1.5 times anchor length. Three components are presented in the simulation model: concrete block, screw anchor and fastened steel plate. To save computational cost, only half of the system is simulated and the symmetry boundary condition is introduced. The symmetry boundary condition is, theoretically, not applicable due to the shape of helix. Taking into account some preliminary simulations and the fact that the helix influence is very local, after comparison of the simulated failure processes to experimental data, the symmetry condition for screw is accepted. In order to simulate the interaction between concrete and screw, the penalty contact model is used, as shown in Figure 4. The friction coefficients are defined based on experimental data. The applied tensile load is transferred from anchor to concrete through the contact on the surfaces of the thread. The numerical investigation is conducted using a nonlinear finite element program The pre-stress is applied in the upper part of the screw to simulate the stress situation due to the anchor`s installation. The value of the prestress is defined on the applied torque moment in experiment. Pullout load is controlled by the displacement at the top surface of the screw to capture the softening behavior of the structure. The concrete material is modeled with a damage plasticity model. The most important features of concrete under uniaxial tension, uniaxial compression and confined compression are included in the model. The crack band method is used for the objectivity with respect to different finite element meshes [7]. A typical benchmark to validate the simulation system has been published in previous work [8]. For all simulations in this study, the material properties for concrete are as listed in Table 1. The screw anchor and steel plate are modeled as an elasto-plastic material and the material parameters are shown in the same table. Material Table 1: Material properties Concrete Steel Young s modulus [MPa] Poisson s ratio Tensile strength [MPa] 2.22 Compressive strength [MPa] 26.9 Yield strength [MPa] 750 Fracture energy [N/mm]

7 Yijun Li, Sandeep Patil, Bernhard Winkle and Tobias Neumaier the bottom of the screw is about to be closed. The pressure distribution in the sheardominant part is reduced due to the shear failure occurring in the concrete. The pressure in the concrete cone area stays almost the same as in load step E. 5 CONCLUSIONS In this study, the screw anchor for concrete is numerically investigated. Based on the simulated load-displacement curve, the loading process is divided into four phases. The damage and crack patterns in different phases are inspected. More detailed study shows that the reason for the phase s variation is the formation of new cracks in the concrete. From the pressure analysis at different load steps, the variation of pressure distribution during pullout loading is analyzed. The relation between damage patterns in the concrete and the pressure distribution is revealed. The analysis results are valuable for a better understanding of the working principle and failure mechanism of concrete screws.
