Elastomeric Bearing Stiffness Report Includes

1. Geometry and Proportioning Table

   • Dimensions of the elastomeric bearing.

2. Material Properties Check

   • As per AASHTO 14.7.5.2, the elastomer shall have a specified shear modulus between 0.080 ksi and 0.175 ksi.

3. Compression Stiffness Calculations

   • The calculated compression stiffness value will be assigned to Tz when the insertion point is chosen for the definition of the elastomeric bearing.

4. Shape Factor Calculations

   • Calculations for the shape factors of both internal and external layers.

5. Effective Compression Modulus Calculations

   • Calculations for the effective compression modulus of both internal and external layers.

6. Compressive Stiffness Calculations

   • Calculations for the compressive stiffness of both internal and external layers.

7. Shear Stiffness Calculations

   • The calculated shear resistance will be assigned to Tx and Ty when the insertion point is chosen for bearing definitions.
