If you have selected the Towers - Splices joint type in Window 1.1 General Data (see Figure 6.5), you can define the bolt parameters in the Definition of Fasteners window.
You can select the Class and Diameter of the bolts in the respective lists. Only bolts of the same type are permitted for the connection.
The check boxes allow you to specify the position of the Shear plane and the bolt type (black bolts or Fit bolts). You can enter the Hole diameter separately.
There is an individual section for each angle plane.
You can use the text boxes to define the Number of rows (currently only one row), the Number of bolts in a row, as well as the respective Distance from the edges and between the bolts. The system sketch on the right illustrates the individual parameters.
