How to define pre-loaded bolts

To define pre-loaded bolts in any relevant manufacturing operations (end plates, connecting plates, gussets, etc.), go to the Shear force transfer option in Bolts tab. When we set Friction as a method for transfer, it means that bolts will be considered as pre-loaded.

 

After analysis, we should be able to see Pre-loaded bolts tab in results tables with relevant SLS check for slip resistance.
