Claims
- 1. A structure for installing a viscous vibration-damping wall between a lower girder and an upper girder, said viscous vibration-damping wall having a housing with an open upper end, an intermediate plate inserted in said housing through said open upper end and a viscous material or a viscoelastic material placed in a gap portion between said housing and said intermediate plate, said housing having a base plate, a pair of steel-made side plates uprightly set on said base plate, and a pair of flange plates disposed on both lateral ends of said pair of side plates, respectively; comprising first high-strength bolt hole portions for connecting a central portion of said base plate to a flange of said lower-floor girder, a pair of first gusset plates provided at both lateral sides of a group of said first high-strength bolt hole portions and suspended downwardly from said base plate, respectively, said first gusset plates each having a face extending in the same direction as that of said intermediate plate, a pair of second gusset plates suspended downwardly from said pair of flange plates, respectively, said second gusset plates each having a face extending orthogonally with respect to a face of said intermediate plate, second high-strength bolt hole portions for connecting said central portion of said base plate to said flange of said lower-floor girder in cooperation with said first high-strength bolt hole portions, said second high-strength bolt hole portions opposing said first high-strength bolt hole portions, a pair of third gusset plates provided on said flange of said lower-floor girder at both lateral sides of a group of said second high-strength bolt hole portions so as to oppose said first gusset plates, respectively, a pair of fourth gusset plates provided on said flange of said lower-floor girder so as to oppose said second gusset plates, respectively, and a fifth gusset plate fixed to a flange of said upper girder, said viscous vibration-damping wall being connected to said lower-floor girder by connecting opposing ones of said first and second high-strength bolt hole portions and opposing ones of said first to fourth gusset plates, and said viscous vibration-damping wall being connected to said upper-floor girder by directly connecting said intermediate plate to said fifth gusset plate.
- 2. The structure for installing a viscous vibration-damping wall according to claim 1, wherein said central portion of said base plate is provided with a joining member for connection to said flange of said lower-floor girder, and said joining member is provided with said first high-strength bolt hole portions.
- 3. The structure for installing a viscous vibration-damping wall according to claim 2, wherein said joining member and said pair of first gusset plates are formed integrally.
- 4. The structure for installing a viscous vibration-damping wall according to claim 1, wherein said base plate includes a pair of step portions, between which said central portion is disposed, said first high-strength bolt hole portions being provided on said central portion.
- 5. The structure for installing a viscous vibration-damping wall according to claim 1, further comprising a rising metal plate installed on said flange of said lower-floor girder, said rising metal plate being provided with said second high-strength bolt hole portions.
- 6. The structure for installing a viscous vibration-damping wall according to claim 1, wherein said first gusset plate is connected to said third gusset plate by means of one-plane friction-type high-strength bolted connection.
- 7. The structure for installing a viscous vibration-damping wall according to claim 1, wherein said second gusset plate is connected to said fourth gusset plate by means of one-plane friction-type high-strength bolted connection.
- 8. The structure for installing a viscous vibration-damping wall according to claim 1, further comprising a pair of splicing plates, said first gusset plate being connected to said third gusset plate by means of two-plane friction-type high-strength bolted connection using said pair of splicing plates.
- 9. The structure for installing a viscous vibration-damping wall according to claim 1, further comprising a pair of splicing plates, said second gusset plate being connected to said fourth gusset plate by means of two-plane friction-type high-strength bolted connection using said pair of splicing plates.
- 10. The structure for installing a viscous vibration-damping wall according to claim 1, wherein said intermediate plate is connected to said fifth gusset plate by means of one-plane friction-type high-strength bolted connection.
- 11. The structure for installing a viscous vibration-damping wall according to claim 1, further comprising a pair of splicing plates, said intermediate plate being connected to said fifth gusset plate by means of two-plane friction-type high-strength bolted connection using said pair of splicing plates.
- 12. The structure for installing a viscous vibration-damping wall according to claim 11, wherein each of said splicing plates includes a central plate portion and a pair of side plate portions separated from said central plate portion.
