Tendon Dialog#

In the SOFiSTiK: Tendon Dialog you can define and modify Tendon elements.

_images/mpic_stendon_dialog.png

Prestressing Framework is divided into following sections:

  • Tendons icon_Tendon_Dialog_Tendons - with the definition of each individual tendon element

  • Cluster Library icon_Tendon_Dialog_Cluster_Library - collection of all grouped definitions

Both Tendons and Cluster library consist of series of input types, which define the geometry and other attributes.

_images/mpic_tendon_dialog_input.png

Note

Changes of input are synchronized in the Tendon and Cluster Library definitions. Please make sure, that you create new type of definition, in case only current tendon should be modified.

Tendon#

Definition#

In this table you can see the summary of each individual tendon. You can make adjustments by selecting individual definition type (e.g. basis geometry and scope) for each data input box.

_images/mpic_stendon_dialog_tendon_definition.png

Basis Geometry#

_images/mpic_stendon_dialog_basis_geometry_definition.png

Type#

Select, duplicate icon_Tendon_Dialog_Type_Duplicate or rename icon_Tendon_Dialog_Type_Rename Basis Geometry definition type of the tendon. You can adjust definition type in Cluster Library icon_Tendon_Dialog_Cluster_Library or directly in Properties window after unlocking the Type Values icon_Tendon_Dialog_Type_UnlockValues.

Properties#

  • Geometric Source

  • Local Modifiers

  • Control Points

  • Orientation - you can define the orientation of tendon profiles according to the tendons middle axis

  • Rotations - you can choose if the placement’s rotation should influence the geometry of the tendons or not

  • Offset U - gives an additional offset in horizontal direction to the curve extracted from geometric source. Value can be constant or connected to variable

  • Offset V - gives an additional offset in vertical direction to the curve extracted from geometric source. Value can be constant or connected to variable

Control Points#

Definition of control points have direct influence to the modification of the Basis Geometry with Local Modifiers.

  • Superimposed - makes a sum of the Basis Geometry Curve with the Curves produced with the Local Modifiers : f(s) + g(s)

  • Composed - makes a chainage of the Basis Geometry Curves applying the Local Modifiers. In other words, Curves from Local Modifiers will ‘override’ the parts of curves defined in Basis Geometry : g(f(s))

    _images/mpic_stendon_dialog_control_points.png

In case the ‘Composed’ option was selected for the curve definition, additional information may be needed to correctly apply the modification of the curves due to the Local Modifiers input. For example, definition of curve domain, that should be influenced by the rounding radius. You can give two stations (before and after the Radius input), that define this domain or use one of the automatic options to restrict the modification.

Restrict at:

  • Inflection (Points) - points at the curve, that change the direction of curvature.

    _images/mpic_inflection_points.png

  • Local max/min - points at the curve that show local minimum and maximum values. For typical tendon definition, these will be high and low points of the cable.

Geometric Source#

Type#

Select, duplicate icon_Tendon_Dialog_Type_Duplicate or rename icon_Tendon_Dialog_Type_Rename Geometric Source definition of the tendon. You can adjust definition in Cluster Library icon_Tendon_Dialog_Cluster_Library or directly in Properties window after unlocking the Type Values icon_Tendon_Dialog_Type_UnlockValues.

Properties#

Source Kind - you can select the kind of data, that will be taken as Basis Geometry

  • Host Axis - axis, that tendons are placed on

  • Guiding Curve - selected curve in model

  • Adaptive Family - extruded point or path along an axis according to the parametrisation of the profile

Element - in case the Guiding Curve is selected as Source, you can pick the Curve in the model as Basis Geometry of tendon > icon_Axis_Selection

Object - in case the Adaptive Family is selected as Source, you can choose between the available object (Point or Path), which are created with Adaptive Reference command. Points or Paths are extruded along the axis creating Basis Geometry

Elongation T#

You can increase / decrease the Curve along its main development

Value - lenght by which the curve will be shortened or elongated

Reduced interval is implemented only when the curve must be shortened (value is positive at start or negative at end)

  • Trim Curve - The curve will be cut at parameter

  • Linear Interpolation - Line from Original End-Point to new location at elongated parameter

  • Extrapolate Start/End - Tangential extrapolation at parameter
