Pretension Bolt Analysis

Hi !

 

I have a structure with bolted joints. I have to simulate the strength of the bolt.

 

First I have applied the Pretension Load.

Then I have applied the working load to the structure in the next step.

 

My objective is to verify the bolt  force is not going above the yield load of the bolt.

I tried this with bolt section force, but it is very much equal to the pretension force. No increase in the section force after applying the working load. Is there any other way to investigate the bolts?

 

 

TIA,

Subhu
