内容記述 | In repair for fatigue cracks or reinforcement by attaching new members on existing steel bridges, welding is performed under restraint by the surrounding members. It is possible that the tensile residual stress generated by welding under the restraint becomes higher than that under the normal conditions without any restraint. For investigating the effect of the restraint on the residual stress generated by welding, a series of thermo-stress analyses were performed on one-pass butt-welding of thin steel plates (6mm) with changing the degree of restraint of the joints. From the results, the tensile residual stress perpendicular to the weld line was largely affected by the restraint when the in-plane displacement of the edge of the plate was fixed. The tensile residual stress varied from 20% to 80% of the yield stress of the material due to the difference of the degree of the restraint. | |||||
