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

It is expected to be more improved if a refined tension constitutive model is used. Index Terms-Fiber beam-column element, nonlinear analysis of NATM tunnel lining, Steel fibre reinforced shotcrete, and Steel supports.
