Tendon > Geometry > Tendon Point New/Modify/Copy

Definition or modification of constraint point for the definition of the tendon geometry.

Setting	Description
Type	Type of the tendon point: Normal: normal tendon point of an internal pre-stressing Line: tendon point type "Line" of an external tendon Line (free Y): point type "Line" with free Y coordinate (external tendon) Line (free Z): point type "Line" with free Z coordinate (external tendon) Intersection point: tangent intersection point (external tendon) Free node at element: additional point for better circle approximation (external) Intersection point (free): free tangent intersection point (external tendon)
Space point or Structure element	The position of the tendon point is either defined in terms of global coordinates or relative to a structural element.

Setting

Description

Type

Type of the tendon point:

Normal: normal tendon point of an internal pre-stressing
Line: tendon point type "Line" of an external tendon
Line (free Y): point type "Line" with free Y coordinate (external tendon)
Line (free Z): point type "Line" with free Z coordinate (external tendon)
Intersection point: tangent intersection point (external tendon)
Free node at element: additional point for better circle approximation (external)
Intersection point (free): free tangent intersection point (external tendon)

Space point or Structure element

The position of the tendon point is either defined in terms of global coordinates or relative to a structural element.

Note: The below described input data refer to element related geometry definition.

Setting	Description
Ref.Elem, (To, Step)	Element number(s) in the structural model to which the tendon geometry definition refers (geometry is defined relative to this element)
Add. point for last element	For From/to/step-definition: an additional point is arranged at the end of the last element
RefSet	If required: Selection of the reference set of the cross section point CS pnt
CS pnt	Eccentricity of tendon can refer to certain additional point in the cross-section In this case the name of the point has to be chosen.
X/L	Point on the reference element (element length related distance from the element begin)
Ey	The vertical offset from the point on the reference element (X/L) to the tendon geometry constraint point (eccentricity: local or global)
Ez	The horizontal offset from the point on the Reference Element (X/L) to the tendon geometry constraint point (eccentricity: local or global)
Relative to Elem	If the button is selected, the eccentricity is related to the element axis
Relative to Node	If the button is selected, the eccentricity is related to the node axis
Relative to CS point	The eccentricity is related to the defined additional cross-section point
Alpha 1	Defined angle in the X/Y plane for the definition of the tangent direction relative to the direction of the respective axis (element, node, CS point)
Alpha 2	Defined angle in the X/Z plane for the definition of the tangent direction relative to the direction of the respective axis (element, node, CS point)
FREE / VALUE	Free: defined angle is not considered Value: defined angle is considered as constraint condition
Relative to Elem	If the button is selected, the angle definition is related to the element axis
Relative to Node	If the button is selected, the angle definition is related to the node axis
Relative to CS point	The angle definition is related to the defined cross-section point axis
Extern	External Element check button - only for tendon points of the "Line" types for defining a straight external tendon section
Number	If Extern is selected: Structural element number of the straight tendon section
Radius	Only for tendon point type Intersection point: Rounding radius of tendon geometry
