Tunnel linings would suffer heavy structural damage or even collapse when exposed to a
long-duration fire. The damage is greatly affected by heating time. In this paper, a theoretical …

This paper presents the full-scale experimental test results of actual RC (reinforced
concrete) metro shield TBM (tunnel boring machine) tunnel linings that are exposed to a …

This paper examines different modeling approaches to simulate the behavior of reinforced
concrete (RC) tunnel slabs under fire during both the heating and cooling phases. Three …

This paper presents comprehensive experimental test results on the behavior of the
reinforced concrete (RC) and the steel fiber reinforced concrete (SFRC) shield TBM (Tunnel …

This work aims to provide a comprehensive procedure for the assessment of structural safety
of tunnel linings exposed to fire. To this purpose, numerical simulations that model the three …

Rectangular shield tunnels have been extensively used in roads, railways, stations, etc. In
this paper, the structural responses of rectangular shield tunnel assembled by composite …

This paper compares the fire performance of bored reinforced concrete tunnel lining
sections under four ground conditions, ranging from shallow soft soil to deep rock. The fire …

Concrete spalling at high temperature seriously jeopardizes the integrity of the entire
structure. Many explanations for the spalling risk exist, but few models can accurately predict …

Safety assessment of tunnel lining after fire is a compulsory work and should be performed
based on thermo-mechanical analysis. In this paper, a theoretical method is presented to …

This paper proposes a transient strain model of concrete with a transient modulus under the
biaxial stress state and a failure criterion for determining the fire resistance of two-way …
