Reactions

The Reactions command serves for displaying nodal reactions and linear intensities on selected point or line supports in model.

Usage

Calculate a FEM analysis of the model
Go to Tree > Results > Supports > Reactions
Set properties of the command to specify mainly:
- selection of members where the results are evaluated
- load type from which the results are derived
- specific result value from the available list to be visualized
Click on [Refresh] action button to display the results

Note: To get general overview about how to work with Result service and its commands, see Results/Basics.

Properties

Category	Property	Description / Notes
Selections	Type of selection All / Current / Advanced / Named Selection / Design group	Specifies on what members the results are displayed See "Type of selection"
Selections	Filter No / Cross-section / Material / WildCard / Layer / Thickness / Type of beam / Pad foundation	Specifies the filter of members on what the results are displayed See "Filter"
Result case	Type of load Load case / Combinations / Classes / Nonlinear combinations / Mass combinations / Stability combinations	Defines for what load the results are displayed. See"Result case"
Extreme	Extreme No / Mesh / Member / Global	Defines the position where extremes of result value are evaluated. note for "extreme no" option: If selected combination or class consist of too many linear combinations and thus it is not possible to display the results in full - conservative method that only displays results for linear combinations causing an extreme response of the structure is used instead.
	Values Rx / Ry / Rz / Mx / My / Mz / Components	See table Values below. Components : possibility to choose more than one value and display them together in 3D window. Only selected values will be displayed in result tables.
	Interval On / Off	Activation of interval of values for displaying in 3D window and in result tables.
	Minimum [ ]	It is available only if Interval functionality is ON. User can define minimal value of interval. This item is unique for every type of unit used in Values.
	Maximum [ ]	It is available only if Interval functionality is ON. User can define maximal value of interval. This item is unique for every type of unit used in Values.
	System Global / Rotated supports	Sets a coordination system which is used as referenced for displaying the results.
	Draw results in nodal supports On / Off	Only results for nodal supports are displayed.
	Draw results in linear supports On / Off	Only results for linear supports are displayed.
Output settings	Print combination key On / Off
Output settings	Display info about used interval On / Off	It is possible to display or not display in header of result tables information about applied intervals.

Values

Value	Description	Notes
R_x	reaction in direction of local axis y	¹⁾ The local axes can be displayed by selecting the corresponding option in the View parameters settings.
R_y	reaction in direction of local axis y
R_z	reaction in direction of local axis z
M_x	reaction around local axis x
M_y	reaction around local axis y
M_z	reaction around local axis z
e_x	eccentricity of reaction Mx / Rz	This items are displayed only in table for Engineering report. It is possible to hide them by switching values to components.
e_y	eccentricity of reaction My / Rz
Components	possibility to choose more than one value and display them together in 3D window. Only selected values will be displayed in result tables.
