The paper presents a numerical modeling of Reinforced Concrete (RC) columns under fire and loading simultaneously. It proposes a concrete model at high temperature considering both transient strain and load path, which is an improvement of the concrete model in EC2. The parameters of the concrete model are tuned so that they are suitable for the concrete materials that are commonly found in China. The concrete model is implemented in the FE software SAFIR, which is developed in the University of Liege by Prof. J. M. Franssen for calculation of structures in fire. The paper continues to validate the material models by experimental results of restrained concrete columns under fire conditions.
