The beams and columns exposed to compartment fire are subjected to severe thermal stress and large deformation and the development of local buckling is expected. Especially, the outer column is subjected to large bending moment and the inner column is subjected to small bending moment. To investigate the column deformation capacity at elevated temperature, two kinds of experiments are carried out about H shaped and box shaped columns made of fire resistance steel. The one is pure compression test for the load bearing capacity of inner column and the other is beam-column test for the bending deformation capacity of outer column. Then, numerical analysis of beam-column test is carried out on the basis of pure compression test and good agreement is ascertained between the numerical and the experimental results.
