Bolt Properties in a Probabilistic Analysis

If you are performing a Probabilistic analysis with SWedge, the following bolt properties (except for User-Defined bolt type) can be defined as random variables.

• Material Capacities specific to the bolt property type
• Bond Length for grouted dowels
• Shear Strength if Use Shear Strength is checked

Constant Bolt Properties

The following bolt parameters CANNOT be defined as random variables for a Probabilistic analysis (i.e. only a single constant value can be defined for each parameter, for a given probabilistic simulation):

• Bolt Orientation Efficiency Method

Using the Statistics Dialog

Clicking the Stats button in a dialog to specify the distribution characteristics for all the properties in the dialog.

The Statistics dialog allows you to specify the distribution characteristics for all variables quickly in table format. By default, the option is selected in the dialog, meaning that the Rel. Min and Rel. Max values are equal to 3x the Std. Dev. In this window, you can edit the seeder properties manually, copy the table of properties to the clipboard, export the properties to Excel, or paste properties from the Clipboard.
