Abstract:
The bridge design concept described makes use of unique features of rubber bearings to introduce overall economies in construction by a favourable and adjustable distribution of external forces from the superstructure to the substructure. Additionally, rubber bearings of limited shear deflection can be applied to a bridge of twice the length of superstructure available by conventional design methods.
