N2 - Owing to strong nonlinearity of shotcrete and difficulty of determining the equivalent material properties of steel-shotcrete composites for numerical analysis, methods are required to estimate nonlinear behavior of steel-shotcrete composite in the computational aspect efficiently. In this study, the behavior of steel-shotcrete composites, main primary supports in the NATM tunnel, are estimated by finite element method using the fiber beam-column element. The numerical results are compared with results of uniaxial and flexural test. Results of comparison show that finite element analysis of using fiber beam-column element can be an efficient tool of estimating the steel-shotcrete composite as the primary support in the NATM tunnel.
