What is Nonlinear Fire Analysis of Cut-and-Cover Tunnels about?

1. The document describes nonlinear structural analyses of a 2-cell cut-and-cover tunnel exposed to fire using both beam and plate finite element models. 2. Thermal analyses were conducted on concrete samples of varying thicknesses exposed to the ZTV-ING fire curve to determine temperature distributions over time. 3. Nonlinear thermo-mechanical analyses were performed on 2D models of the tunnel in 10-15 minute time intervals over 90 minutes, accounting for reduced material stiffness and strains at high
