Input Name | Description |
---|---|
Distance from start / end | The distance from the end of the member to the center line of bearing. This value is also used as s for the plain bearing capacity calculation |
Length | The length of bearing area in the longitudinal direction |
Width | The width of the bearing area in the transverse direction |
Friction Coeff. | The coefficient of friction |
A1 / A2 | The ratio of the bearing areas as defined in PCI 5.5.1. |
Bearing Points | The number of points at each end of the member which support the component. IE for a double T this would be 2. |
Nu / Vu Ratio | The ratio used to calculate Nu and Cr. This ratio is only applied to the sustained load. |
User defined Cr | If the user selected ‘Override Cr’ they can input their own Cr value to use. Note that the Nu / Vu ratio will still be used to compute Nu. |
Plain Bearing Capacity
The plain bearing capacity is calculated based on Ch. 5 Section 5.5.1. When calculating the Cr term, the distance from the start (or end) is used for the s term in Eq. 5-61.
