Building and infrastructure damages, such as tunnels, have become a more important issue
because of the continuous expansion of rural and urban constructions. It is well-known that …

Explosive spalling is a major threat to fire safety of reinforced concrete structures. A deep
understanding of pore pressure build-up is important for evaluating and mitigating this …

In this paper, we present a self-propagating Strong Discontinuity embedded Approach
(SDA) for quasi-brittle fracture. The method is based on the Statically Optimal Symmetric …

The cracking elements (CE) method is a recently presented self-propagating strong
discontinuity embedded approach with the statically optimal symmetric (SDA-SOS) …

This paper aims at developing an efficient numerical model to numerically reproduce the fire-
induced spalling process taking place in concrete and to investigate the underlying …

All crack models developed to date can be classified into discrete-and continuum-based
approaches. While discrete models are advantageously capable of capturing the kinetics of …

High ground temperature has become a common problem during the development of long,
deep and complex geological tunnel. Sangzhuling tunnel is a key program in the …

Fire is a significant hazard to the safe operation of tunnels, causing extensive damage and
deterioration to the lining. This research proposed a prototype test of a shield tunnel …

The exceptional behavior of concrete under fire conditions is often jeopardized by concrete's
propensity to spall. While published works seem to agree on the complexity and …

Fire-loaded concrete structures may experience explosive spalling, ie, violent splitting of
concrete pieces from the heated surfaces, greatly jeopardizing the load carrying capacity …
