摘要： The present invention provides a joining structure capable of greatly improving the proof stress and the fatigue property by alleviating the stress concentration and residual stress caused by welding heat at one or both ends of a tabular member.In the present invention, one or both ends 4 of a tabular member 3 such as a reinforcing rib, fixed to the surface of a structural member 1 in the direction of the principal stress of the structural member 1 so as to protrude in the shape of T, is/are bent in a direction deviating from the direction of the principal stress and, by this, the rigidity at the end(s) 4 of the tabular member 3 decreases and the stress concentration is alleviated. It is preferable to bend one or both ends of a tabular member 3 in the shape of an gradual curve and to the extent that each bent end is formed at a right angle to the direction of the principal stress. The tabular member may have the shape of a flat plate, or it may be bent so that it has the shape of U or V as a whole. Further, the tabular member may be welded to a structural member or formed as an integral part of a structural member.
摘要翻译：本发明提供一种接合结构，其能够通过减轻板状构件的一端或两端由于焊接热引起的应力集中和残余应力而大大提高耐候应力和疲劳特性。在本发明中，一端或两端4 在结构构件1的主应力方向上以T形突出的方式固定在结构构件1的表面上的平板状构件3（例如加强筋）沿偏离的方向弯曲从主应力的方向，由此，平板状构件3的端部4处的刚性降低，并且应力集中得以缓解。优选将平板状构件3的一端或两端弯曲为逐渐曲线的形状，并且使弯曲端部成为与主应力方向成直角的程度。板状构件可以具有平板的形状，或者可以弯曲，使得其整体具有U或V的形状。此外，板状构件可以焊接到结构构件上或形成为结构构件的组成部分。
