Extract system Response Spectra at decoupled connection points

The capability of producing FRS at some points is sometimes needed to analyze small bore branches. Generally, the small bore branches could be decoupled from the headers for seismic analysis, but these lines shall be evaluated separately using the header FRS at the connection points. Piping stress analysis software such as PIPESTRESS (PepS) can create such FRS at branch connections. So, I was wondering if AutoPIPE can do the same.

    Hello Voria - What is the specific use case here? I can appreciate that there would be some advantages to considering the large bore first, but since the small bore will influence the branch connections wouldn't it just be simpler and quicker to combine both together to give a true representation of the piping system. Features like this probably are left over from the days when we didn't have the computer memory or power to analyse both together, but now we do not have any such restrictions.
