Abstract

A general numerical model was developed based on the finite element method (FEM) in bi-dimensional domain, as well as the computational program PFEM_2D T. The model is capable of determining temperature fields for different types of structures and boundary conditions, accomplishing linear or non-linear analyses. Furthermore, the model carried out thermal analysis of structures under different situations (fire, hydration heat and ambient temperature and solar radiation - environmental action). The PFEM_2D T is based on the technique Object-Oriented Programming (OOP).The computational model PFEM 2D T was applied to the structural members under fire conditions and it has been validated using the comparison of its results of temperature distribution with those obtained by other thermal studies of structural members under fire condition. The thermal numerical model is capable of predicting the temperature distribution of structural members under fire conditions and it is more an alternative by using advanced methods to determine thermal behaviour of structures under a fire situation.
