With the rapid urbanization and development of metropolises, urban road tunnels have been
constructed at an increasing rate, significantly alleviating urban traffic pressure, and …

Automatic real-time fire characterization is a crucial requirement of future smart firefighting.
This work proposes a novel computer vision method to automatically measure the fire heat …

Fire hazards are a major threat to tunnel structures; however, the existing understanding of
the behavior of tunnel linings under fire is limited, which restricts cost-effective and safe …

Investigating fire effects is a continuing endeavour in the research and practice communities
concerned with the design and safety of shield tunnels. This paper aims to provide 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 …

Concrete made with recycled concrete aggregates (RCA) presents particular properties that
may lead to a specific behaviour under fire conditions, including the spalling risk. The …

As a significant infrastructure hazard, fires in tunnels have brought about a great deal of
economic and social losses each year. From a holistic tunneling design perspective, it is …

Experiments were conducted to investigate fire-induced explosive spalling in conventionally
reinforced normal weight concrete panels that emulate tunnel liners. Nineteen specimens …

In view of the global–local property and multiscale characteristics of spalling behavior in
tunnel lining, superposition-based phase field fracture model is introduced within a …

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 …
