Unri Bridge
Project description
The Unri Bridge is located in South Korea’s southern part in Pungam-dong, Seo-gu, Jeollanam-do.
The bridge was opened in 2004 to relieve traffic in the Gwangju area and designed as a steel bridge.
It is 134.8 m long and its deck is supported by two piers on PHC pile foundation, where the strength of the concrete is as high as 27 Mpa.
mageba scope
mageba supplied 16 pieces of RESTON-PENDULUM DUPLO bearings, with vertical load capacities of 4,500 kN (horizontal forces: 287 kN and displacement: 100 mm) and 2,000 kN (horizontal force: 75 kN and displacement: 100 mm) to fortify the bridge against seismic activities.
By applying the calculated effective stiffness of the used RESTON-PENDULUM DUPLO into the structural analysis to accommodate possible seismic movements, the calculation model proved that the bridge can be safely maintained in the event of an earthquake.
