N2  - SAFIR is finite element software for the thermal and mechanical analysis of structures exposed to fire. For mechanical analysis, a library of different elements is available in SAFIR: truss, beam, etc. In order to increase SAFIR's capabilities, a quadrangular shell element has been implemented. This element is not subject to 'locking' (or over-stiffness) in the case of 'membrane bending'. Different material models can be used. These are plasticity models based on the von Mises surface (for isotropic materials), plus a Rankine tension cut off for concrete. The parameters of the models as well as the hardening laws have been chosen in such a way as to fit the recommendations of Eurocode 2 and 3 for uniaxial stress-strain curves of concrete and steel under fire condition. Some verification and validation examples at room and at elevated temperatures are presented.<p />
