摘要： PROBLEM TO BE SOLVED: To increase absorbing capacity of energy by installing a bracket on a structural element of a joint part, respectively supporting central parts of rod type plastic behavior elements and connecting shaft end parts of a large number of the plastic behavior elements to each other by a connecting plate. SOLUTION: A large number of plastic behavior elements 13a, 13b of rod type spring plastic materials to bend, shear and deform are inserted into a large number of through holes of brackets 11, 12 respectively. Additionally, plate surfaces of the brackets 11, 12 respectively support a rod type intermediate part of the plastic behavior element 13, and they fix both end parts on a connecting plate 15. Thereafter, absorption of energy due to transmission of a load from one constitutional element to the other constitutional element and deformation is carried out by double bending deformation of the plastic behavior element 13 inserted into the brackets 11, 12. Consequently, a plasticizing member 10 absorbs energy by deformation of the plastic behavior element 13 at the time when an earthquake works. Continuously, the new plasticizing member 10 is installed by removing a bolt nut 14, the brackets 11, 12 and the plastic behavior element 13 after plastic deformation. Consequently, it is possible to easily repair and restore it.
