Profile Polyline Properties

Setting	Description
Group	Allows for selection of a profile polyline group which will control some of this object’s properties. If a group is selected, the following properties are set by the assigned group: Elevation Reference Elevation Optimization Properties See Tendon Parameters Group for additional information about groups.
Elevation	The vertical distance from the elevation reference to the centroid of the tendon’s strands, also referred to as CGS (center of gravity of strand). Note: This version of RAM Concept measures the top and bottom cover to the CGS of the strands. Future versions will allow inputting of duct dimensions and allow a top and bottom cover to the outside of the duct to be input. Note: The CGS is not the same as mid-depth of a bonded tendon’s duct.
Elevation Reference	The choices are: Absolute: the elevation relative to the zero datum. This is not recommended other than for very complicated geometry. Above Soffit: The elevation is measured from the soffit elevation to the CGS of the tendon. Above Surface: The elevation is measured from the surface elevation to the CGS of the tendon. The value is almost always negative. Top Cover: The elevation is measured from the surface elevation to the CGS of the tendon. The value is always positive. Bottom Cover: The elevation is measured from the soffit elevation to the CGS of the tendon. The value is always positive.
Profile Location	Determines the orientations of the created tendon half-spans (and the corresponding inflection point location). The choices are: Support Span The support profile polylines are displayed graphically as solid lines on plan, while the span polylines are displayed as dashed lines.

Group

Allows for selection of a profile polyline group which will control some of this object’s properties. If a group is selected, the following properties are set by the assigned group:

See Tendon Parameters Group for additional information about groups.

Elevation

The vertical distance from the elevation reference to the centroid of the tendon’s strands, also referred to as CGS (center of gravity of strand).

Note: This version of RAM Concept measures the top and bottom cover to the CGS of the strands. Future versions will allow inputting of duct dimensions and allow a top and bottom cover to the outside of the duct to be input.

Note: The CGS is not the same as mid-depth of a bonded tendon’s duct.

Elevation Reference

The choices are:

Absolute: the elevation relative to the zero datum. This is not recommended other than for very complicated geometry.
Above Soffit: The elevation is measured from the soffit elevation to the CGS of the tendon.
Above Surface: The elevation is measured from the surface elevation to the CGS of the tendon. The value is almost always negative.
Top Cover: The elevation is measured from the surface elevation to the CGS of the tendon. The value is always positive.
Bottom Cover: The elevation is measured from the soffit elevation to the CGS of the tendon. The value is always positive.

Profile Location

Determines the orientations of the created tendon half-spans (and the corresponding inflection point location). The choices are:

Support
Span

The support profile polylines are displayed graphically as solid lines on plan, while the span polylines are displayed as dashed lines.
