| Concrete f'c: |
Specified concrete strength. |
| Size of concrete support: |
Size of concrete support used in calculating allowable concrete bearing strength. |
| Area of concrete support: |
Area of concrete support used in calculating allowable concrete bearing strength. |
| Eff Area of support (A2): |
Area of the portion of the supporting surface that is geometrically similar to and concentric with the loaded area. |
| Area Required for Bearing: |
Area of plate required by concrete for bearing. |
| Area of Plate (A1): |
Actual area of plate. |
| Square Root of (A2/A1): |
Used in calculation of allowable concrete bearing; limited to 2.0 maximum. |
| Allow. Factored Bearing Stress: |
For Allowable Stress Design, this is the allowable concrete bearing stress based on ACI allowable values. |
| Actual Factored Bearing Stress: |
For Allowable Stress Design, this is the actual factored concrete bearing stress. |
| Actual Bearing Stress: |
For Allowable Stress Design, this is the unfactored concrete bearing stress used in sizing the plate thickness. |
| 0.60Pp: |
For LRFD 3rd, this is the allowable design bearing load on the concrete. |
