Horizontal force dispersing rubber bearing (NR)
Reliable support for superstructure
The rubber shoes are made from vulcanized rubber and steel plate laminate to support the bridge superstructure.
Horizontal load dispersion protects both superstructure and understructure
Horizontal load generated in the bridge superstructure during seismic motion is dispersed across multiple understructures via the shearing rigidity of the rubber, helping to prevent damage and structural failure.
Adjustable natural period
The natural period of the superstructure is calibrated to parameters such as the size and shape of the bridge and the strength of the foundations to achieve optimum dispersion and buffering performance.
