Abstract (EN): Real fire events have shown that shear failure of reinforced concrete (RC) columns due to thermal elongation of the adjacent beams and slabs is not a rare event. In this work evolution of shear forces on the elements of a RC frame are traced during a standard fire. As the advanced thermo-mechanical analysis used is unable to predict shear failure, a simplified method is proposed, based on the guidelines drawn in Eurocode 2 (EC2) for verification of shear strength of RC elements under ambient temperature, but extended to account for the detrimental effects of fire induced temperatures on the resistances of the stirrups (or links) and diagonal concrete struts. Shear forces are computed in all beams and columns of the analyzed RC frame with the FEM code SAFIR, and the corresponding shear strengths are evaluated in a post-process fashion with the proposed simplified method.
