Brace-type damper mounting structure

Abstract

There is disclosed a brace-type damper mounting structure, which provides a highly-reliable stabilized joint member to produce sufficient damper functions against external turbulent force such as earthquakes and wind, and is so rational as to achieve higher workability. According to the mounting structure of the present invention, brace-type dampers are placed in V-shaped arrangement, for instance, to the inside of frames composed of columns and beams of a reinforced concrete structure. When the brace-type dampers are placed in the frames of columns and beams, one end of each brace-type damper is connected to a band-shaped reinforcing plate united to the outer surface part of each column through a gusset plate with a pin, separately from each beam. The other end of each brace-type damper is connected to a gusset plate, which is projecting from the upper surface of an anchoring member embedded in each beam, with a pin.

What is claimed is:  
     
         1 . A structure for mounting a brace-type damper with a damper incorporated in a brace to the inside of each frame of columns and beams of a reinforced concrete structure, the brace-type damper mounting structure comprising a reinforcing plate united to an outer surface part of each column making up said frame, separately from each beam, wherein one end of said brace-type damper is connected to said reinforcing plate.  
     
     
         2 . A brace-type damper mounting structure according to  claim 1 , wherein said reinforcing plate is united to each column at an upper or lower end of said column.  
     
     
         3 . A brace-type damper mounting structure according to  claim 1 , wherein said reinforcing plate is formed in the shape of a band so as to be placed around an outer column surface as equivalent to said outer surface part of each column into one body.  
     
     
         4 . A brace-type damper mounting structure according to  claim 1 , wherein said reinforcing plate is formed in the shape of a band so as to be placed around an outer surface part in a column section as equivalent to said outer surface part of each column into one body.  
     
     
         5 . A brace-type damper mounting structure according to  claim 3  or  4 , wherein studs serving as shear connectors are mounted to the inner surface of said band-shaped reinforcing plate.  
     
     
         6 . A brace-type damper mounting structure according to  claim 3  or  4 , wherein inner partition plates located in the section of said column are provided on the inside of said band-shaped reinforcing plate.  
     
     
         7 . A brace-type damper mounting structure according to  claim 6 , wherein studs serving as shear connectors are mounted to said inner partition plates.  
     
     
         8 . A brace-type damper mounting structure according to  claim 6 , wherein said inner partition plates are placed in parallel to one-directional side plates making up said band-shaped reinforcing plate.  
     
     
         9 . A brace-type damper mounting structure according to  claim 6 , wherein said inner partition plates are placed in cross-shaped arrangement in said band-shaped reinforcing plate.  
     
     
         10 . A brace-type damper mounting structure according to  claim 6 , wherein said inner partition plates include an inner partition plate continuously extending to a joint portion of said reinforcing plate with one end of the brace-type damper.  
     
     
         11 . A structure for mounting a brace-type damper with a damper incorporated in a brace to the inside of each frame of columns and beams of a reinforced concrete structure, the brace-type damper mounting structure comprising an anchoring member embedded in each beam making up said frame, wherein one end of said brace-type damper is connected to a joint member, which so extends from said anchoring member as being projected from the upper or lower surface of each beam.  
     
     
         12 . A brace-type damper mounting structure according to  claim 11 , wherein studs serving as shear connectors are mounted to said anchoring member.  
     
     
         13 . A brace-type damper mounting structure according to  claim 11 , wherein said anchoring member is made up of shape steel.  
     
     
         14 . A brace-type damper mounting structure according to  claim 12 , wherein the shape steel making up said anchoring member has flanges placed in parallel to a joint surface of said brace-type damper with each beam.  
     
     
         15 . A brace-type damper mounting structure according to  claim 11 , wherein flanges for preventing said anchoring member from being shifted in the axial direction are mounted to said anchoring member.  
     
     
         16 . A brace-type damper mounting structure according to  claim 15 , wherein said flanges of said anchoring member extend toward the upper or lower surface of each beam so as to be one with said joint member.
