Abstract:
Numerical simulation has become a powerful tool for supporting the development of innovative fastening products. The information on the failure mechanism developing during the load transfer from fasteners to concrete can be obtained and analyzed by simulation, which offers the basic requirement for designing innovative fasteners. During the last 15 years Hilti Corporation has developed a simulation tool based on the finite element method and concrete material models to support the fastener design process. In this paper various simulation examples for typical post-installed anchors, particularly for adhesive anchors, are presented. Numerical simulations are carried out for single anchors and anchor groups consisting of four adhesive anchors loaded in tension. The simulation results are discussed and compared with experimental data. The comparison shows a good agreement.
