How to define preloaded bolts

To define preloaded bolts in any relevant manufacturing operations (endplates, connecting plates, gussets, etc.), go to the Shear force transfer option in the Bolts tab and choose the option Friction.

To code-check ULS and SLS, you need to run the analysis twice (or make two copies of the model) - one time for ULS and second time for SLS, because each of the limit states has different safety factor.

Open the Code setup and modify the safety factors for each limit state, as well as friction coefficient and pretension force factor according to the code, as described in the video.

In the Pre-loaded bolts results tab you can read the slip resistance force.
