Banded Tendon Polyline and Distributed Tendon Quadrilateral Properties
| Setting | Description |
|---|---|
| Group |
Allows for selection of a banded tendon or distributed quadrilateral
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. |
| Tendon Specification Type | Determines the mode for specifying strand quantities that go into the generated tendons. The choices are: |
| Effective Force | Only enabled when "force" is selected for "Tendon Specification Type". For banded tendon polylines, this value represents the total effective force to be generated in the banded group. For distributed tendon quadrilaterals, this represents the effective force per unit width of slab to generate in the distributed tendon array. |
| Number of Strands | Only enabled when "strands" is selected for "Tendon Specification Type". For banded tendon polylines, this value represents the total number of strands to be generated in the banded group. For distributed tendon quadrilaterals, this represents the number of strands per unit width of slab to generate in the distributed tendon array. |
| Max Strands/Tendon | For banded tendon polylines, this value defines the maximum number of strands to put into a single generated tendon. |
| Layout Type | For banded tendon polylines, this value defines the layout type of the generated tendons. The choices are: |
| Tendon Spacing | Defines the lateral spacing between generated tendons. |
| Layout Width | For banded tendon polylines, defines the total width of the generated tendon layout when "width" is selected for "Layout Type". The width includes a half space on each side of the outermost generated tendons. |
| Tendon Type | For banded tendon polylines, defines the behavior of the banded tendon polyline and the properties of the generated tendon. The choices are: |
| Added Tendon Generation | For banded tendon polylines, controls the behavior of the automatic generation of added tendons to balance forces at connected banded tendon polyline ends. The choices are: |
| Added Tendon Length | For banded tendon polylines when "Fixed Length" is selected for "Added Tendon Generation", controls the length of the automatically generated banded tendon polyline. |
| Added Tendon Span Fraction | For banded tendon polylines when "Span Fraction" is selected for "Added Tendon Generation", controls the length of the automatically generated banded tendon polyline as a function of the span containing the joint that the added tendon is attached. |
| PT System | The label used to identify the PT system for the generated tendons. The label is not necessarily the size and type of strand. The Materials Specification defines the PT system properties. It is possible to mix systems in a single tendon parameters layer. |
| Inflection Point Ratio | Determines the distance, x, from end 1 in the span to the point where the tendon curvature changes sign. The inflection point ratio is the ratio of x to the distance from end 1 to end 2. A value of 0.2 places the inflection point 10% of the span distance from end 1 if end 2 is at midspan. This is a commonly used value. |
| Harped | Specifies the tendon segment as having a straight profile (as opposed to a parabolic profile). |
