STATIC TIME HISTORY - SACs

Hello,

How do I account for the locked-in stresses in a Topside model. Can SACs do a time history analysis. I am modelling a brown field modification to a topside model (oil and gas).

I will very much appreciate if I can be pointed to the right direction.

regards,

  • SACS can perform Time History analysis,

    Btw, it depends on how complex of your problem.

    For brown field modification, I think it is costly to perform in Time domain unless it is really required.

    If you would like to consider locked-in stresses in the element before you start to modify the model.

    You can do stage analysis by using SACS combine module. Sequence of loads can be analysed and combined them to be the final solution. Btw, this is based on linear elastic.
