Member stresses - values

Returns a stress value for the selected member.

RSA_BAR_STRESS_AT (Stress type, Bar no., Case no., Case component no., Position, Relative)

The RSA_BAR_FORCE_AT formula syntax has the following arguments:

Stress type

The following types of stresses are available:

FXSX
axial stress
SHEARY
shear stress - TY
SHEARZ
shear stress - TZ
SMAX
maximal normal stress
SMAXMY
maximal stress due to bending moment MY
SMAXMZ
maximal stress due to bending moment MZ
SMIN
minimal normal stress
SMINMY
minimal stress due to bending moment MY
SMINMZ
minimal stress due to bending moment MZ
TORSION
torsional stress - T

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 first 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_STRESS_AT("FXSX",6,8,2,0.8,TRUE) - specifies a value of the axial stress for the member number 6, for the load case number 8, for the component number 2 and at the position 0.8 given as relative value

Result (value):

-39354.74613
