[en] This paper is devoted to nonlinear numerical modeling of reinforced concrete columns subjected to fire. In this work we analyze reinforced concrete columns loaded by eccentric compressive forces and exposed to a standard fire. That the columns have an extremely important role in building, the verification of fire resistance in fire conditions is crucial. The analysis is divided into two steps. In the first step we make the thermal study of column. It follows the temperatures depending of time that we use in the second stage for the mechanical study, where we get the variation of different parameters such as bending moment, stresses, displacements and tangent modulus.
