Descrição

In this work an analytical model for obtaining the local bond stress-slip relationship of hooked-end steel fibres is presented. The mathematical representation of the pullout problem is described and the numerical algorithm of the model is detailed. Furthermore, the performance of the developed model is assessed using results obtained in fibre pullout experimental tests.
