Uniform Loads - CAESAR II - Help

Defines uniform load data. Select or clear this option by double-clicking the Uniform Loads check box on the Classic Piping Input dialog box.

The software defines the uniform load as force per unit length of pipe (F/L) unless you specify gravitational loading (G) as a load multiplier.

Typical units (depending on your unit system):

• lb/in

• kN/m

• N/m

• N/cm

• N/mm

The Uniform Loads tab controls up to nine uniform load vectors. These uniform loads are applied to the entire current element, as well as all subsequent elements in the model until you change it.

UX, UY, and UZ

Specifies the X, Y, and Z components of each uniform load vector. You can type components for up to nine vectors.

G's

Specifies a uniform load in terms of gravitational loading. You most often use uniform loads in g’s for static earthquake loadings. You can specify g's individually for each vector.

Seismic Wizard

Opens the Seismic Wizard.

You can specify G’s as the default for each vector by selecting Uniform load in G’s for Environment > Special Execution Parameters . For more information, see Special Execution Parameters.

Examples

For uniform loading in force per unit length (F/L), you can specify a snow load of 8.0 pounds per foot (assuming units of pounds per inch in a Y-up coordinate system) as follows:

or as:

For uniform load in G’s, you can specify a 1.0g load in the horizontal X direction as:

You can specify a 1.0g load in the minus Y direction, which is the same as the pipe weight load in Y-up coordinate system.
