摘要： PROBLEM TO BE SOLVED: To provide joint structure capable of greatly enhancing a bearing force and fatigue performance by reducing stress concentration at the stopping end of a plate-shaped member and residual stresses caused by the heat of welding. SOLUTION: The plate-shaped member 3 such as a reinforcing rib projecting in the form of a T from the surface of a structural member 1 in the direction of main stress has its end 4 curved in a direction away from the direction of the main stress. The end 4 is therefore low in rigidity to reduce the stress concentration. The end 4 of the plate-shaped member 3 is preferably bent into a curve until it becomes perpendicular to the direction of the main stress. The plate-shaped member may be a flat plate or be curved into a U- or V-shape as a whole. The plate-shaped member may be formed by welding or integral forming.

摘要： PROBLEM TO BE SOLVED: To provide a structure of column base excellent in durability to be used for various poles of an indication pillar, electric-pole, or the like, iron towers, buildings, bridges, etc., and the construction method thereof. SOLUTION: A structure of column base having a base plate 2 for bolt connection at the lower end of the column base is provided with an upper column base member and a lower column base member 1b, and the lower column base member 1b is continuously provided to the base plate 2 for bolt connection to form the bottom part of a hollow pipe whose inside diameter is larger than the outside diameter of the lower end of the upper column base member, and the prescribed length of the lower end part of the upper column base member is inserted into the inside of the lower column base member 1b, and a castable hardener 3 is filled between the inside surface of the hollow pipe of the lower column base member 1b and the outer surface of the lower inserting part of the upper column base member to integrally combine the lower column base member 1b and the upper column base member.

摘要： PROBLEM TO BE SOLVED: To provide a connected structure capable of greatly improving strength and fatigue performance by relieving a concentrated stress and a residual stress due to welding heat in the end of a platelike member. SOLUTION: A reinforcing rib 3 protruded in a T-shape, extending in the principal stress direction of a structural member 1 is welded to the surface of the structural member 1. The end in the principal stress direction of the reinforcing rib 3 is bent in the direction escaping along the surface of the structural member 1 from the principal stress direction. In this way, the end 4 becomes low in the rigidity and hence, the concentrated stress is relieved. It is preferable to relieve and bend curvedly the end 4 of the platelike member 3 and also bend it to form a right angle to the principal stress direction. In the claim 7, the end of an anchor bolt is bent in the direction escaping from the principal stress direction to obtain the same effect. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide the junction structure of a structural member and a tabular member in which strength and fatigue performance are made largely better than conventional devices.
SOLUTION: In the junction structure, another tabular member for installing a joint or installing a secondary member is welded and projected to the surface of the structural member. A reinforcing rib bent in a U shape or a chevron shape along the surface of the structural member and projected in a T shape is used as the tabular member, and the center line of the U shape or the chevron shape is directed in the main stress direction of the structural member. The stress concentration and welding-heat residual stress of a reinforcing-rib mounting section are relaxed largely by the structure.
