<P>PROBLEM TO BE SOLVED: To provide a connection-reinforcement metal fitting for wooden buildings, which can improve energy absorption performance at the stage of its tabular bent portion's elastic deformation without increasing a deformation load that causes deformation of the bent portion, and also can prevent occurrence of interference with a brace or an out-of-place deformation. <P>SOLUTION: A connection-reinforcement metal fitting comprises a tabular bent portion 5, which is composed of crest parts 9 and troughs 10 alternately formed with slope faces aslant against an acting direction of a load F, absorbing deformation energy by elastically deforming; and is installed to a connection part formed by connecting structural members. The tabular bent portion is composed of bend groups 5A and 5B each consisting of a plurality of bends, and flat link parts 11 sequentially connecting these bend groups, with height of the crest parts measured from the troughs varying between the adjacent bend groups along an acting direction of the load. <P>COPYRIGHT: (C)2012,JPO&INPIT |
