| Abstract: | Through designing the recipe and construction, the physical properties,anti-press and antishear properties of the bridge bearings have come up to the standard issued by the Ministry of Communication. The limiting compression strength satisfies the demand of use completely. It ensures vertical stiffness and horizontal flexibility that compression elastic modulus is far bigger than shear elastic modulus. The antishear capability of the bridge bearing itself come up to the demand of the application. |
