NONLINEAR FINITE ELEMENT ANALYSIS OF SHOTCRETE LINING REINFORCED WITH STEEL FIBRE AND STEEL SETS (2013)
This paper deals with a shotcrete lining with steel sets. The nonlinear analyses of a reinforced shotcrete lining are performed by using fiber beam-column element, which is a forced based element on the Euler-Bernoulli beam theory. The constitutive model is developed to describe the tensile behavior of shotcrete material reinforced with steel fibre. The finite element models of shotcrete lining with steel fibre and H-section reinforcements are created. The numerical results are compared with results of 3 point flexural tests. The proposed approach shows that it can estimate the shotcrete lining with steel fibre and reinforcements approximately. It is expected to be more improved if a refined tension constitutive model is used.
