Transient Analysis and Bolt Preload

cx g

Hi, I'm running into a problem while doing a transient analysis. I want to do a transient analysis with bolt preload, I set up two loadsteps, bolt preload and transient analysis, but I can't link them together.
I tried STATSUB (PRELOAD) but it doesn't work.
Please refer to attachment.

Please help me in this regard ...

This is very urgent and important ...

Hi. Please see the deck file attached running step 1 as a pretension load and step 2 applying the load using the same tabled1 you have created. Use TS time = SUB for TLOAD or adjust the curve in TABLED1 from 1 to 4s.
Use NLSTAT for pretension load step.
For the non-linear transient use Force instead of DAREA, use CNTNLSUB to continue from load step 1 and add pretension load step to statsub(pretens) field to fix the pretension load applied at step 1.
Thank you,
