| Abstract | ||
| The present paper aims to investigate the impact of fire on the behavior of concrete structures such as tunnels. In this paper, the non-uniform work hardening plasticity model (Willam-Warnke five-parameter model) was adopted as yield and failure criteria for concrete. The tunnel was investigated after being exposed to a fire, by means of a FE 3-D model. Moreover, the behavior of the tunnel during heating and cooling processes was studied. Furthermore, the tunnel was also analyzed by a FE 2-D model, in order to make comparisons between the two models. | ||
