To investigate the influence of high-frequency induction heating for paint-coating removal on deformation and residual stress of steel structural members, a series of experiment and analysis was carried out. The heating of 160 to 260 ℃ generated the out-of-plane deformation of 0.13 mm to 0.52 mm in the steel plates with the thickness of 9 mm, 16 mm, and 25 mm. The maximum tensile residual stress was around 200 N/mm2 in the heating region. The residual stress distribution in the heating region was not uniform and varied largely. The stress distribution might be strongly influenced by the change in the running speed of heating device.
