Seismic spherical hinge bearing - spherical hinge bearing manufacture

Performance parameter index of seismic damping bearing
  Vertical bearing capacity: 0kn-80000kn
  Vertical pulling force: 500-80000kn
  Horizontal shear force: 500-80000kn
  The above three types of forces can be selected by corresponding combination, but the design needs to be reviewed separately in special circumstances

  Design angle: 0

05 (low temperature - 60 & deg; ~ 25 & deg;)
The elastic coefficient shall be selected according to the overall calculation of the project, so as to achieve uniform internal force in the static state, lower dynamic action and lower peak stress

The reinforcement in the column shall refer to the research and analysis results in the design of this support, that is, within the height range of 0
25b to 0
6b from the column top along the column axis to the column base (B is the column section width), increase the configuration of horizontal stirrup section, and the increase amount shall be determined according to the bearing capacity analysis results

Finished fixed spherical hinge support for roof Klqz4300kn-gd bearing reaction (vertical bearing capacity) is divided into 15 levels: 1500KN, 2000kN, 2500kN, 3000kN, 4000kn, 5000kN, 6000kn, 7000kN, 8000kN, 9000kN, 10000kN, 12500kn, 1500KN, 17500kn and 20000kn
