Run a new static analysis for WRC 297 loads - CAESAR II - Reference Data

CAESAR II Applications Guide

Reference Data

With the nozzle specification and the node number change for deflections at the vessel nozzle, the piping system model is ready for a new analysis.

Check for errors

  1. Click Start Run , or select File > Error Check to start the error checker.

    The Errors and Warnings report displays.

    The error checker produces two notes regarding the hanger sizing. Additionally, if the vessel node number is not included on any piping element, the software displays a warning regarding the specification of a vessel node number in the WRC 297 input. This is acceptable because the displacements of the vessel node (node 6000) are defined.

    The report lists the flexibilities extracted from WRC 297:

    • Axial stiffness of 319, 226 lb./in.

    • Longitudinal bending stiffness of 291,036

    • Circumferential bending stiffness of 58,665

      These values are much less than the magnitude of the default rigid stiffness, which is 10E12.

      You can now perform a second static analysis on the model.

Reanalyze the model

  1. Click Batch Run to run the static analysis.

    The software performs a new analysis for the piping system and load cases.

    When complete, the Static Output Processor displays.

  2. Select the following options:

    • For Load Cases Analyzed, SHIFT-click to select the OPE, SUS, and EXP load cases

    • For Standard Reports, CTRL-click to select Displacements, Restraint Summary, and Stresses.

    • For General Computed Results, select Hanger Table W/Text

These options simplify report creation, but create the following extra reports that have no meaning: EXP + Displacements, EXP + Restraint Summary, and OPE + Stresses.

  1. For Output Viewer Wizard, click Add, and then click Finish.

    After processing completes, a tabbed window with all the reports displays.
