Angle or Commands > Angle defines the default element strong axis orientation and places the following card in in the Card Stack pane:

Define the element strong axis

  1. Select the appropriate row in the Card Stack pane.

  2. Use the needed command from the Insert menu to place the ANGLE card in the needed position. For more information, see Insert Menu.

  3. Click Angle .

    The ANGLE card is added to the Card Stack.

  4. Click to expand the ANGLE card and view the properties.

  5. Add values to the ANGLE properties.

  6. Click Save to finish.

    The CAESAR II Error Checker automatically checks the model for errors.

Define structural columns when the strong axis is not parallel to the global X-axis

Use Angle with a structural column when the strong axis of the column is not parallel to the global X-axis. When the strong axis of the column is parallel to the global Z-axis, redefine the default orientation to ANGLE=90. Define the column elements then use ANGLE again to reset the default orientation to its original value of ANGLE=0.0.

Define the angle of rotation

Orient and Angle both define the angle of rotation in degrees about the element center line from the standard orientation to the element strong axis. Use Orient to define this angle for a single element or for a group of elements, and Angle to define the default orientation to its original value, such as, ANGLE=0.0.

The default orientation angle is.

Find the positive angular rotation

Use the right-hand rule to find positive angular rotation. Extend the thumb along the element in the direction of the to node. The fingers of the right hand circle in the direction of a positive orientation angle.

Determine the default element orientation

  • If the member is vertical, then the default strong axis is along the global-X axis.

  • If the member is non-vertical then the default strong axis is perpendicular to the center line of the member and in the horizontal plane of the member.

The strong axis for the WF shape is:
