The dialog box of this mode is much similar to the Bolted Connections mode. The mode enables you to perform checks of the following types of connections with high-strength bolts with controlled tightening:
The connection type is selected by clicking the respective button of the Type of Connection tab. Friction coefficients μ and safety factors γh, defined by Table 36* of SNiP II-23-81* (Table 39 of SP 53-102-2004, Table 39 of SP 16.13330, Table 1.12.2 of DBN B.2.6-163:2010, Table 16.2 of DBN B.2.6-198:2014), are calculated by the application on the basis of a cleaning method selected in the Method of cleaning the surfaces to be joined drop-down list and an adjustment method selected with a radio button. To calculate γh, the difference between the nominal diameters of holes and bolts under static load is assumed to be 1...4 mm.
The Properties tab contains tables for entering data on the dimensions of the joint and forces acting in it (it is assumed that the point of application of forces is the center of mass of the section). This tab is also used to specify the beam profile.
The set of checks depends on the type of the connection and the set of loads it is subjected to.
The connections are checked for:

The Interaction Curves tab displays interaction curves of force factors enclosing an area of the load-bearing capacity of the friction connection . This tab is absolutely identical to that of the Bolted Connections mode.
