THE HYSTERETIC DAMPER FOR SEISMIC RETROFIT

摘要

The present invention relates to a hysteresis damper for seismic reinforcement, for this purpose, a steel beam constituting an inner core, a reinforcing pipe disposed around the steel beam, and concrete filled in the reinforcing pipe to prevent buckling of the steel beam A mortar and a pair of first bodies formed of a connecting portion connected to one side of the steel beam and connected to a bracket coupled to a corner of a pillar and a beam; And a second body in which a high displacement portion is built-in so that both sides of the first body are addressed via a low displacement portion, and a relatively large displacement is offset therein, but the second body is made of steel. A beam, a reinforcing pipe disposed around the steel beam, and a concrete mortar filled in the reinforcing pipe, the steel beams of the second body are separated into two, and are addressed to each other with a high displacement portion therebetween. Each steel beam embedded in a concrete mortar is configured to be separated from a concrete mortar so that it can flow in the longitudinal direction, and the low displacement portion is coupled between a coupling flange fixed to the reinforcing pipes of the first and second bodies, and each coupling flange. It is characterized by being interposed and made of an elastic member corresponding to a relatively small displacement.
