CAEPIPE Analysis

CAEPIPE performs linear and non-linear static and dynamic analyses of 3D piping systems using optimized, tested and verified solution algorithms using some of the most advanced programming methods available. Below, you will find a sampling of the types of analyses you can do with CAEPIPE.

Seismic Response Spectrum Analysis

  • Spectrum input can be in the form of:
    • Frequency (or period) versus Displacement
    • Frequency (or period) versus Velocity
    • Frequency (or period) versus Acceleration
  • Linear or logarithmic interpolation
  • Multiple units supported
  • Spectra can be entered interactively or through a text file
  • Missing mass (left-out force) correction can be included.

Combination Method can be:

  • SRSS
  • Absolute Sum
  • Closely Spaced Modes as per USNRC Reg. Guide 1.92
  • Naval Research Laboratory (NRL) Sum

Time History Analysis

    Time functions can be input inside CAEPIPE or imported from a text file

Harmonic Analysis

Force Spectrum Analysis

  • Force spectra functions can be input inside CAEPIPE or imported from a text file or can convert existing time functions into force functions.
  • Pressure Relief Valve loading analysis.
