Connection forces - input / forces

The Connection forces command serves for displaying connection forces in ends of 1D members connected to selected node in structure. As prerequisity it is necessary to define this node in functionality Connection input

Usage

1. Calculate a FEM analysis of the model
2. Go to Input panel > Connection forces - input
3. Define node of interest and other parameters of connection.
4. Select this Connection input entity.
5. Go to Results > 1D members > Connection forces
6. Set properties of the command to specify mainly:
   • result case
   • extreme
7. 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.

Connection forces - input

Workflow is definition of connection input node and then 2 possibilities are available:

1) switch off 1D member of interest in properties - in connection result table there will be displayed connection forces of this member missing in zero balance in the node

2) switch on only members of interest in properties - in connection result table per members there will be displayed connection forces of these 1D members

Properties

Category	Property	Description / Notes
Name		Name of connection
Node		Node where connection input is defined
Members	"name of members" On / Off	List of 1D members connected to this node. Continuous 1D members are not taken into account.
Geometry	System GCS/ LCS
Eccentricity	Eccentricity ex [m] Eccentricity ey [m] Eccentricity ez [m]	Definition of eccentricity of connection point

Connection forces - results

Properties

Category	Property	Description / Notes
Selections	Type of selection All / Current / Advanced / Named Selection	Specifies on what members the results are displayed See "Type of selection"
	Filter No / Material / WildCard / Layer	Specifies the filter of members on what the results are displayed See "Filter"
Result case	Type of load Load case / Combinations / Classes / Nonlinear Combinations	Defines for what load the results are displayed. See"Result case"
Extreme	Extreme No / Node / 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 R_x / R_y / R_z / M_x / M_y / M_z/ Components	See table Valuesbelow. 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 LCS mesh element / Global	Sets a coordination system which is used as referenced for displaying the results.
Output settings	Forces per member On / Off	Extra table with connection forces for all connected 1D members is displayed in preview
	Display info about used interval On / Off	It is possible to display or not display in header of result tables information about applied intervals.
Drawing Setup	Display values On / Off Display units On / Off Display value name On / Off Envelopes drawing 0 to extreme / min to max
