钢结构由钢板和加强筋拼装而成，采用角焊施工。角焊产生了离面变形。研究了预置变形法作为一种平面外变形预防方法的有效性。阐述了只有将预置变形作为初始变形，与角焊产生的变形相同时，才能防止离面变形。在角焊中，角变形大于纵向弯曲变形。提出了焊接表面反面加热防止角变形的方法，并说明了该方法的适用性。
Fillet welding was perfonned in constructing the steel structures which were assembled by plates and stiffeners. Out-of-plane deformation was generated by fillet welding. Validity of the preset distortion method, which had been well known as a prevention method of outof-plane deformation, was investigated. It was elucidated that out-of-plane deformation could be prevented only when the preset distortion was given as an initial deformation which was same as deformation generated by fillet welding. In fillet welding, angular distortion was larger than longitudinal bending deformation. A prevention method of angular distortion, in which the opposite side of the welding surface was heated, was proposed and the applicability was shown.
