Computational analysis of reinforced concrete structures subjected to fire using a multilayered finite element formulation
TL;DR: In this article, an approach using corotational layered beam is proposed to mitigate fire risk in reinforced concrete (RC) structures and appropriate structural resistance against it has to be ensured.

Spalling and pore pressure in HPC at high temperatures
TL;DR: In this article, an original device was designed in order to make simultaneous measurements of pressure and temperature at various positions in a concrete specimen (30×30×12 cm3) heated on one face up to 800°C.

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.

Pore Pressure and Drying of Concrete at High Temperature
TL;DR: In this paper, a mathematical model for water transfer in concrete above 100°C is developed, and the pore volume available to free water increases as dehydration due to heating progresses and as pore pressure is increased.

Predicting the fire resistance behaviour of high strength concrete columns
TL;DR: In this paper, a numerical model, in the form of a computer program, for tracing the behavior of high performance concrete (HPC) columns exposed to fire is presented. But the model is limited to the case of HPC columns and cannot be used to predict the fire resistance of any value of the significant parameters, such as load, section dimensions, fiber reinforcement, column length, concrete strength, aggregate type, and fiber reinforcement.

Hydrothermal model for predicting fire-induced spalling in concrete structural systems
TL;DR: In this article, a one-dimensional numerical model to predict fire-induced spalling in concrete structures is presented, which is based on pore pressure calculations in concrete, as a function of time.
