Journal ArticleDOI
Numerical analysis of hygro-thermal behaviour and damage of concrete at high temperature
TL;DR: 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.
Journal ArticleDOI
Modelling of hygro-thermal behaviour of concrete at high temperature with thermo-chemical and mechanical material degradation
TL;DR: In this article, a mathematical model for analysis of hygrothermal behavior of concrete as a multi-phase porous material at high temperatures, accounting for material deterioration, is presented, starting from macroscopic balances of mass, energy and linear momentum of single constituents.
Journal ArticleDOI
Hygro‐thermo‐chemo‐mechanical modelling of concrete at early ages and beyond. Part I: hydration and hygro‐thermal phenomena
TL;DR: In this article, a new numerical model of hygro-thermal and hydration phenomena in concrete at early ages and beyond is presented, where all changes of material properties are expressed as functions of hydration degree, and neither as maturity nor as equivalent hydration period.
Journal ArticleDOI
Thermo‐hydro‐mechanical analysis of partially saturated porous materials
TL;DR: In this paper, a fully coupled numerical model is presented to simulate the slow transient phenomena involving heat and mass transfer in deforming partially saturated porous materials, making use of the modified effective stress concept together with the capillary pressure relationship.
Journal ArticleDOI
Hygro-thermo-chemo-mechanical modelling of concrete at early ages and beyond. Part II: Shrinkage and creep of concrete
TL;DR: In this paper, a mechanistic model of hygro-thermo-chemical performance of concrete at early ages has been introduced, and in particular, evolution of its strength properties (aging) and deformations (shrinkage and creep strains), described by using the effective stress concept.
