Abstract: | This paper represents an analytical model to predict the influence of the fibre geometry on the pull-out behaviour of various geometrical hooked end steel fibres. The model is established based on the concept of a frictional pulley along with two, three and four plastic hinges to simulate the mechanical anchorage effect provided by the hook. The mechanical contribution of the hook is a function of the cold work needed to straighten the fibre during the pull-out. The input parameters used in this model are directly related to geometrical and mechanical properties of each fibre. Model predictions are validated against experimental results for single fibre pull-out tests, and very good agreement is shown. |
