This study aims at examining the relation between the performance of steel members and the material properties. Specimens composed of H-shaped beams and box columns were subjected to seismic motions by means of shaking table test. The range of temperature was set from -50℃ to +15℃ in order to include -15℃, which is the transition temperture obtained from Charpy impact test. All specimens showed high deformation capacities above -20℃ in temperature. When temperature was below -30℃, brittle fracture occurred and the specimen showed the progress of deterioration in strength and deformation capacity according to the temperture.
