Bolts

This mode is used to select bolts for the structure being designed. The selection is available for four groups of structures according to Table 57* of SNiP II-23-81*, Annex D of SP 53-102-2004 or SP 16.13330, Annex C of DBN B.2.6-163:2010, Annex A of DBN B.2.6-198:2014.

The Service Conditions tab contains three groups of data:

• Type of structure, where you can select one of two cases, defined by the codes, according to the requirements imposed on durability of the bolted joint.
• Performance conditions of bolts, where you can select a type of performance conditions for a bolt in a joint. The Shear only option is the recommended one for all joint types provided by the Bolted Connections mode.
• Climatic region according to GOST 16350-80, where you can specify one of the temperature modes of operation defined by the codes (it is not used if DBN is selected).

Once you have specified all the data in the first tab, open the next one by clicking on the Bolts tab.

The Bolts tab contains a list of recommended bolt classes and their properties.

The Standards and Codes tab provides the user with the reference information necessary for the design of a bolted joint.
