dc.description.abstract	Structural elements of reinforced concrete, in general, present good performance in case of fire. However, more recent structures have adapted new types of concrete (high strength, self-compacting, etc.) presenting different thermo mechanical behaviour, acquiring special importance the study of spalling. One of the most common procedures to minimize this events is the addition of polypropylene fibres (PP) to natural components, reducing the internal void pressure of the material through the channels created by the fusion of the fibres. The experimental study of concrete under fire conditions and the development of new numerical models has allowed the assessment of more or less complex phenomena to determine temperature evolution and other state variables, enabling different levels of approaches, using coupled or uncoupled field interaction (thermal, mechanical, hydrodynamic, chemical). This investigation studies the thermal performance of a two dimensional model, using nonlinear and transient finite element analysis.	pt_PT
