Successful Conclusion of Kunming Changshui International Airport Terminal 2 Project Observation & Seismic Isolation, Energy Dissipation & Vibration Control Technology Exchange

- The isolation layer utilizes lead-core rubber bearings (with diameters ranging from 1200mm to 1600mm), ordinary rubber bearings, and elastic sliding bearings. For the roof area above the high-speed railway tunnel, specialized seismic-vibration dual-control bearings are adopted, supplemented by viscous dampers to regulate the displacement of the isolation layer.
- To control the seismic displacement difference of isolation layers at different elevations, the stiffness of the first-floor structure has been enhanced: shear walls are partially installed, and column sections are enlarged.
- In response to the risk of excessive isolation layer displacement under extremely rare earthquakes, dual displacement control measures are in place: U-shaped special metal deceleration and limiting devices reduce structural movement speed via a stiffness mutation mechanism; meanwhile, metal folding damping buffers are mounted on the building’s outer walls to effectively absorb energy from potential collisions.
- For the high-speed railway’s main line area: a combined bearing system is used, integrating a steel spring unit (with an isolation frequency of 4Hz) in series with a horizontally slidable spherical hinge.
- For the arrival and departure line area: another combined bearing system is adopted, pairing a horizontal limiting high-elasticity unit (with an isolation frequency of 5.5Hz) in series with a horizontal rubber isolation unit.
