<p><P>PROBLEM TO BE SOLVED: To provide a damping frame of an effective and proper structure, which enables a steel column and a steel beam to be joined together by a simple structure, and which enables the rational installation of a damping element. <P>SOLUTION: The steel column 1 and the steel beam 2 are joined together by semirigid jointing. An earthquake-resisting brace 3 is joined to a joint between the steel column 1 and the steel beam 2. The earthquake-resisting brace 3 combines a damping element, which exerts an energy absorbing function by being plastically deformed when undergoing a predetermined axial force, with an earthquake-resistant element which exerts strength while remaining in an elastic deformation range even if the damping element is plastically deformed. The steel column is composed of H-shaped steel or box steel; the steel beam is composed of H-shaped steel; bolting makes a flange of the steel beam joined to the steel column via a joint member 4, composed of a split T or an angle, without the intermediary of a diaphragm; and bolting makes the earthquake-resisting brace joined to the joint via the joint member. A joint position of the earthquake-resisting brace is set so that a line of action of the axial force of the earthquake-resisting brace can pass through the center of the joint between the steel column and the steel beam. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
