Bearings: Specify the bearings for which the report will be generated.

Info

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.
