Member forces - values

Returns a force value for the selected member.

RSA_BAR_FORCE_AT (Force type, Bar no., Case no., Case component no., Position, Relative)

The RSA_BAR_FORCE_AT formula syntax has the following arguments:

Force type

The following types of forces are available:

• FX

  reaction force FX

• FY

  reaction force FY

• FZ

  reaction force FZ

• KY

  elastic coefficient KY

• KZ

  elastic coefficient KZ

• MX

  reaction moment MX

• MY

  reaction moment MY

• MZ

  reaction moment MZ

Note: If you type an argument in the formula manually, enclose the text in quotation marks. You can also select or type a cell address (for example A1) which the data will be loaded from.

Bar no.

The following input methods are available:

• Text - type a text (any character string) and enclose it in quotation marks, for example: "ALL" - all members in the project or "1 2 3" - specified list of members
• Number - type an integer
• Cell address - select or type a cell address (for example A1) which the data will be loaded from
• Graphical selection - select this option in the dialog or type "@"
  Note: If members are selected graphically in Autodesk Robot Structural Analysis Professional, then the program returns information for the first member selected.

Case no.

The following input methods are available:

• Text - type a text (any character string) and enclose it in quotation marks, for example: "ALL" - all cases in the project or "1 2 3" - specified list of cases
• Number - type an integer
• Cell address - select or type a cell address (for example A1) which the data will be loaded from
• Graphical selection - select this option in the dialog or type "@"
  Note: If cases are selected graphically in Autodesk Robot Structural Analysis Professional, then the program returns information for the first case selected.

Case component no.

It is a number of the case included in a combination.

The following input methods are available:

• Number - type an integer
• Cell address - select or type a cell address (for example A1) which the data will be loaded from
• Graphical selection - select this option in the dialog or type "@"
  Note: If cases components are selected graphically in Autodesk Robot Structural Analysis Professional, then the program returns information for the case component selected.

Position

It is a distance (x) which is defined by default as an absolute value (a coordinate of the point along the member length). After selecting the relative value in the dialog, a value from the interval <0, 1> should be specified. The position value must be positive.

The following input methods are available:

• Positive value - type a value (positive real number)
• Cell address - select or type a cell address (for example A1) which the data will be loaded from

Relative

The following input methods are available:

• Check box - select the Relative option in the dialog (then argument in the formula set as TRUE)
• Text - type TRUE (relative value) or FALSE (absolute value)

Formula:

RSA_BAR_FORCE_AT("MY",8,3,6,1.78,FALSE) - specifies a value of the MY moment for the member number 8, for the load case number 3, for the component number 6, and at the position 1.78 given as absolute value

Result (value):
