A model consists of structural objects, loads and finite elements. This chapter summarizes the definition ways, the properties and the features of the structural objects.

Depending on the current FEM-Design Module (license you have), the available Object types are different. Although the structural objects are real 3 dimensional objects, they are 1D members and 2D planar elements (because of the finite element method) having sectional (thickness, profile etc.) and material properties. So, they can be defined as lines or regions. Some elements like point supports can be defined as points.

Table: Structural Objects and their main properties

The commands for defining structural objects can be started from the 1584606358359-405.png  Tabmenu. Each command has a Tool palette with the customizable element properties (cross-sections, materials, stiffness values etc.) and the definition tools of the element geometry and position (direction).

Properties

Tool palette contains all customizable structural properties. The main properties can be set directly in the tool palette and all properties can be set in the dialog opens by clicking on the Default settings button. The settings dialog and fields keep the last set property values by element types (beams, columns, plates etc.)

1584606450182-329.png

Figure: Setting part of Tool palette

Cross sections

FEM-Design offers the possibility to add any cross-section type/shape (Section) to beams, columns and truss members.

warning.pngTo avoid design failures of concrete, steel and timber bars (section type and material do not fit), the program checks the section type - material compatibility while setting the properties. The program sends an error message when it finds incompatibility definition at closing the settings dialog. But, the so-called General material (defined by the user) can be added to each section types.

The Section tabpage of the settings dialog contains predefined cross-sections. Unique profiles and shapes can be define by their parameters (parametric shapes) in New> Size or with the 1584606589609-328.png  FEM-Design Section Editor. The following table sums the available cross-section types.

Figure: Safety factor calculator

In Material settings dialog different creep coefficients can be specified for Serviceability Limit State (SLS) and Ultimate Limit State (ULS). It has some consequences in load case calculation and results:

  • All load cases are calculated twice (first with the SLS Creep coefficient, than with the ULS Creep coefficient.
  • The displayed displacements are the results of the SLS calculation.
  • The displayed internal forces, reactions are the results of the ULS calculation.

“Properties” Tool

1584614046306-822.png       With the Properties tool of a tool palette, the properties of a selected object or objects can be inquired and edited in dialog format (similar to Default settings).

1584614094257-717.png

Figure: Modifying object properties (e.g. cross-section of a selected beam)

Modify properties by “Quick menu”

Alternative way of modifying object properties is to select any object by right click, or more objects of the same type by box, then click “Propertiesfile:///C:/Users/Fredrik/AppData/Local/Temp/msohtmlclip1/01/clip_image084.png in the Quick menu to check/modify its/their properties. This function works for structural objects, loads or design elements.

1584614131051-278.png

“Pick properties” and “Copy properties”

With these functions the properties of an object can be copied to others of the same type, or picked to use as default. Both can be found in the Tools menu and in the toolbar as well.

1584614148289-653.png

To copy properties with the Copy properties (1584614182261-577.png ) function, first select the source object, then one or more objects to which the properties are to be applied.

1584614161427-800.png

Pick properties (1584614198743-481.png ), when used on an object (of the same type as in the active editing dialogue) will update the default settings for its type.

warning.png

Pick properties can only be used when Define is selected in an editing window, otherwise it is disabled.

1584614287014-961.png

Copy and Pick properties work according to the following rules:

  • Generally, the properties defined by the property dialogue will be picked or copied.
  • They are only available in the 3D Structure and Plate modules.
  • ID will not be copied.
  • Load case of loads will not be copied.
  • Varying shell thickness and surface load value will not be copied.

Numbering

Structural elements with an ‘Identifier (. position number)’ will have an automatically or manually assigned position number.

1584614344163-874.png

The position number will be 0 upon creating the object and will be automatically set to another value in the following cases:

  • before creating a list
  • using the Find tool
  • before calculation

User can manually set position numbers by Tools/Numbering… 1584614355603-251.png  tool.

1584614361983-249.png

Use 1584614366715-716.png  for Manual position numbering

  1. type required position number into the Position no. textbox
  2. select option for handling position number conflicts
  3. select object(s) to set position number for

1584614375936-666.png

warning.png

In case more objects are selected, the first one gets the position number typed by the user and for the next ones it is increased automatically.

To set position number of component objects, like edge connections, corbels, post-tensioned cables, punching regions, the Select component (…)  auxiliary option has to be checked.

Objects with manually set position number can be highlighted by checking the last option of the tool window.

1584614416851-247.png

The position number can be reset to zero by choosing Reset 1584614431314-981.png  option then selecting one or more objects.

Automatic numbering 1584614436757-234.png  sets position number automatically for all objects in the database except the ones with manually set position number.

The option to Lock numbering can be accessed by clicking its icon 1584614443611-700.png  in the same Tool window.

1584614453969-412.png

When the numbering of a selected object type is locked, the position number of individual elements will remain the same. The maximum position number is saved for all IDs, so position numbers less than that will not be used in the future, even if some items are deleted.

This means all the element types with their numbering locked will retain their original ID, even after refreshing the numbering (either manually, or automatically).

1584614475497-574.png

Display Settings of Structural Elements

The display properties of the structural elements can be set at the Settings > All… > Display.

The available options depend on the current FEM-Design module.

1584614523032-825.png

Figure: Settings options affect on the appearance of the structural elements

  • Drawing elements
    With the Show end points of line option you can show (or hide) the insertion points of planar structural objects, their holes and bar objects (beams, columns etc.). These points are visible in all display modes, but the Wireframe mode without displaying the elements’ thickness gives the clearest appearance of them.
    1584615910533-659.png
    Figure: Insertion points displayed in Wireframe mode
    light.png

    By showing the insertion points you can also detect the unnecessary (for example accidentally) defined points, which may cause “too refined” finite element mesh in planar structural elements. The unnecessary points can be deleted with editing tools (Edit menu) which can be applied for region elements (such as plate, wall regions etc.). For example, stretch the unnecessary points outside the host region, and then cut the stretched region part(s) with the Split tool of the Modify region (Edit menu) or with the Hole tool of the structural planar object.

    1584615989630-259.png
    Figure: Unnecessary definition points detected visually

    With the Fill-up with color option the planar objects (plate, wall, drawing regions) can be displayed with their reference plane as colored surface or with their contour lines only. Applying the fill colors is useful to display holes/openings clearly. The filling color of an element is the default color of the Object layer includes the element. It can modified at the layer settings by element types (Plate, Wall etc.) or with the Color option of the Change properties tool (Edit > Properties) by elements (independently from their types).

  • Display local system
    The local co-ordinate system of the structural elements can be displayed with the Display local system option by element types. The size of the local system symbol can be set at the Size option. The color of the local system axes can be set at Local systems setting. The default colors are: green for the local x’ axis, red for the local y’ axis and blue for the local z’ axis.

    Figure: Local co-ordinate system displayed on screen by element types
     
  • Special display settings of walls
    With the Display wall base line option (3D Structure and Predesign modules only) the bottom end of the walls can be displayed as a hatched surface.
    By inactivating the Display wall height option (Plate module only) only the reference support line (as hatched surface) can be displayed without showing the height-extension that is out from the plates’ calculation 2D plane.

    1584616265108-734.png
    Figure: Special display options of walls
  • Special display settings of bar elements
    The Display section shape option shows the applied section of the bar elements as a colored symbol in the middle of the bar reference lines. The size (Scale), the filling (Fill) and contour (Border) colors are customizable. Although, section shape symbols are visible in most of the different display modes, their “best” display mode is the Wireframe mode without displaying the elements’ thickness.

    The Display connections option shows the end connection property (see Beam, Column or Fictitious bar connection settings) of the bar elements. Only the free end motion components can be displayed as arrows, where a simple arrow shows a motion component by its direction and a double-headed arrow shows the axis direction of a rotation component. The fix (rigid) end connection components are never displayed. The color of an end motion component equals with the color of the proper axis of the host bar element’s local system (see before, Display local system). The size of the symbols can be set at the Size option.
    1584622743015-422.png
    Figure: Special display options of bar elements
     
  • Layer, color and pen width
    All elements are placed (and grouped) on Object layers according to their type. So, for example, columns are on the “Columns” layer and the walls are on the “Walls” layer. The default color and pen width of elements’ contours/reference lines are represented by their host layers. For example, by default, walls are red, if the color of the “Walls” layer is also red.
    1584622795988-176.png
    Figure: Layer-system of structural objects

The default color of an object can be modified independently from their types with the Color option of the Change properties tool (Edit > Properties).

Color schema

This feature lets the users to navigate a model easier, by allowing them to fully customize element colors. These options can be accessed through the Tools à Colors menu command, or by clicking on their icon (1584622927900-699.png ) in the toolbar.

Mode determines the attribute on which the color coding is based. When None is selected, the default colors for object types will be used.

1584622957109-755.png

1584623007739-957.png

For each object type, the following attributes are available:

Beam, column and trussID, Material, Cross-section
Plane plate and wallID, Material, Thickness
Profiled plate and wallID, Material, Cross-section
Timber panelID, Material
Edge connectionID, Rigidity type

The Manage button can be used to save a specified color coding system. These can be selected afterwards from the drop-down list to the left from the Manage button. Schema color is saved only for a given project.

Clicking the Apply button will apply the color code to the model. Enabling the Auto apply checkbox will apply any changes automatically.

When a custom color scheme is in use, a legend window will be displayed. With the Position button, the placement of this window can be specified; it can even be hidden. By default, the legend is displayed in the bottom left corner of the screen.

Colors, borders, and their line types (with thickness) can be modified by clicking on the Edit palette button. In the dialog box, all parameters can be set for every value of the specified attribute (ID, Material or Thickness). It is possible to save these settings separately to be used in another color scheme.

The Settings button will allow you to save your color scheme to a file (*.cpal) or as default, or load another schema.

warning.pngWhen a color scheme is saved, only the colors and their order will be stored, values need to be specified each time.
light.pngPen (line weight) can use pixels as well as millimeters. A positive number means millimeters, while a negative one will give the line width in pixels. A line weight given in millimeters will remain the same in the documentation. When pen size is given in pixels, the line weight will remain the same on-screen, regardless of zoom level.

Geometry

The definition modes and the available shapes of structural elements’ reference line or reference plane depend on:

  • The structural type: 1D Member or Planar Object, and
  • The current FEM-Design module.

The Tool palette of a structural element contains only the available modes. The next table summarizes the geometry possibilities by structural elements.

Hole

1584706736189-590.png       Holes, openings and cuttings can be added to reference regions (Plate, Wall and Surface support) with the Hole tool. The following geometries can be used for holes:

The steps of a hole definition:

  1. Select the host region with mouse-clicking. Clicking a region places the UCS into the region plane, so giving hole coordinates needs only X and Y values from the UCS origin.
  2. Define the geometry of the hole with one of the following geometry modes:
    1584706750496-863.png  Rectangular
    1584706782578-809.png  Circular

Figure: Hole tool can be used to edit region geometries as cuttings

Holes can be easily copy inside a region or among regions with same reference plane position with the Copy command (Edit menu). It is recommended to display only the regions’ reference plane (inactive Display thickness option) to easily select the contour of the hole you would like to copy. To set the distances/new positions, the UCS has to be in the plane of the host region(s).
