abstract = {The aim of this work is to investigate the effects of restrained thermal elongation on the behaviour of Reinforced Concrete (RC) beams and columns in a natural fire environment. A finite element model, capable of analysing the behaviour of restrained RC elements from pre-fire stages to collapse is used. Through the results of the parametric study, it is shown that conventional failure based on material failure and deflection criteria may not be conservative under some fire scenarios. Based on the strength and restraining forces failure criteria, the fire resistance of RC slender beams and columns was found to decrease by increasing the axial restraint stiffness. It was also found that the conventional method based on standard fire exposure may not be conservative for columns if the resulting fire has a decay phase similar to the severe fire scenario used in this study. &copy; 2014 Taylor & Francis Group.<br/>},
