Open type damping system for seismic retrofit of existing structure and constructing method for the same

摘要

An open damping system for seismic reinforcement of an existing structure and a construction method thereof according to the present invention include: an inner frame formed to correspond to the rim of the opening of the existing structure to surround the opening of the existing structure; an outer frame formed to surround the inner frame and joined to the outer wall of the existing structure; A plurality of installed between the outer frame and the inner frame to damp vibration, one end of which is hinged to the inside of the outer frame and the other end is hinged to the outside of the inner frame along the vibration damping direction. four dampers; It includes; a bonding portion for bonding the external frame to the existing structure. As described above, using the open damping system for earthquake-resistant reinforcement of an existing structure according to the present invention and a construction method thereof, there is an advantage in that the existing structure can be efficiently reinforced with an earthquake-resistance and a feeling of openness can be improved.
