You can adhere to nonlinear piping code compliance requirements by doing the following:

  1. Performing an operating and sustained analysis of the system and including with each case the effect of nonlinear restraints.

  2. Subtracting the sustained case displacements from the operating case displacements to find the displacement range.

  3. Calculating the expansion stresses from the displacement range solved for in step 2.

CAESAR II uses this method for calculating the expansion stress range. In addition, CAESAR II scans your input and recommends load cases and combinations for performing the operating, sustained, and expansion stress calculations. This recommendation is useful when performing spring hanger analysis of a multiple operating case system.
