Enter the forces and moments acting on the nozzle or attachment. A stress summation is performed, and stress intensities are checked based on the different load cases.

The type of loads and the available load sets depend on the Convention System selection (WRC 107 or Global).

Load Sets

When WRC 107 is selected for Analysis Type, you can enter values in the following load sets:

  • Sustained Loads - (SUS) Primary loads, typically weight + pressure + forces.

  • Expansion Loads - (EXP) Secondary thermal expansion loads.

  • Occasional Loads - (OCC) Irregularly occurring loads such as wind loads, seismic loads, and water hammer.

The software plots one set of loads at a time and only that set can have values. For example, to calculate Expansion Loads, values for Sustained Loads and Occasional Loads must be cleared.

Types of Loads

When WRC 107 is selected for Convention System, the following forces and moments are entered:

Radial Load P

Longitudinal Shear VL

Circumferential Shear VC

Torsional Moment MT

Circumferential Moment MC

Longitudinal Moment ML

When Global is selected for Convention System, forces and moments are entered as X, Y, and Z vector components with respect to the global coordinate system: Global Force Fx, Global Force Fy, Global Force Fz, Global Moment Mx, Global Moment My, and Global Moment Mz.
