Numerical analysis of hygro-thermal behaviour and damage of concrete at high temperature
TLDR
In this article, a computational analysis of hygro-thermal and mechanical behavior of concrete structures at high temperature is presented, and the evaluation of thermal, hygral and mechanical performance of this material, including damage effects, needs the knowledge of the heat and mass transfer processes.Abstract:
A computational analysis of hygro-thermal and mechanical behaviour of concrete structures at high temperature is presented. The evaluation of thermal, hygral and mechanical performance of this material, including damage effects, needs the knowledge of the heat and mass transfer processes. These are simulated within the framework of a coupled model where non-linearities due to high temperatures are accounted for. The constitutive equations are discussed in some detail. The discretization of the governing equations is carried out by Finite Elements in space and Finite Differences in time. Copyright © 1999 John Wiley & Sons, Ltd.read more

Numerical Modeling of Water Transfer in Geomaterials: Application to a Concrete Tunnel Subjected to Both Drying and Liquid Overpressure
Computational analysis of thermo-chemical and mechanical behaviour of tunnels during fire
TL;DR: In this article, a new procedure for structural assessment of tunnel construction during fire is presented, which consists of two steps: the first one deals with a realistic evaluation of thermal fluxes, both convective and radiative, for the whole tunnel.
Dissertation
Coupling between permeability and damage in concrete
TL;DR: In this article, a real-scale hollow cylinder has been instrumented with gauges for studying the evolution of temperature and gas pressure fields inside concrete, and the cylinder was then numerically modelled by means of a thermo-hydro-chemical (THC) and a thermodynamic-mechanical (THCM) model.

A Thermo-Mechanical Model for Fire Exposed RC Structures
TL;DR: In this paper, a model based on a phenomenological approach is presented for the evaluation of the load-carrying behavior of fire exposed reinforced concrete structures and validated by the numerical simulation of fire tests on concrete specimens and of a large scale fire test on a reinforced concrete slab.
