Why limit horizontal shear deformation in laminated elastomeric bridge bearings?
Choices
- (A) Rubber layers roll or delaminate if shear strains exceed elastomer stamina
- (B) Bearings possess unlimited ductility irrespective of shim plates
- (C) Anchor bolts negate sliding demand completely
- (D) Thermal movements never revisit bearing pads after installation
Correct answer: (A)
Rubber layers roll or delaminate if shear strains exceed elastomer stamina
Explanation
Shear caps safeguard shim bonding and dowel punching under thermal cycles.
