The model of integral steel framed structures is built.Finite element method is used to perform numerical simulation of integral structures under fire.Elasto-plastic analysis of thermal stress and deformation is carried out.As a result,the deformation,stress contours as well as the curves of inner force and deflection varying with time are obtained.The behavior of integral structures under different restrained conditions and protection measures are also compared.An approach to numerical simulation is developed for fire-resistant design based on integral structures.
