cPropMaterialGetSSCurve Method

Retrieves the material stress-strain curve.

Namespace:  ETABS2016
Assembly:  ETABS2016 (in ETABS2016.dll) Version: 16.0.0.0 (16.0.0.0)
Syntax
Copy
int GetSSCurve(
	string Name,
	ref int NumberPoints,
	ref int[] PointID,
	ref double[] Strain,
	ref double[] Stress,
	string SectName = "",
	double RebarArea = 0,
	double Temp = 0
)

Parameters

Name
Type: SystemString
The name of an existing material property.
NumberPoints
Type: SystemInt32
The number of points in the stress-strain curve.
PointID
Type: SystemInt32
This is one of the following integers which sets the point ID. The point ID controls the color that will be displayed for hinges in a deformed shape plot.
ValuePoint ID
-5-E
-4-D
-3-C
-2-B
-1-A

Strain
Type: SystemDouble
This is an array that includes the strain at each point on the stress strain curve.
Stress
Type: SystemDouble
This is an array that includes the stress at each point on the stress strain curve. [F/L2]
SectName (Optional)
Type: SystemString
This item applies only if the specified material is concrete with a Mander concrete type.

This is the frame section property for which the Mander stress-strain curve is retrieved.

The section must be round or rectangular

RebarArea (Optional)
Type: SystemDouble
This is the area of the rebar for which the stress-strain curve is retrieved.

This item applies only if the specified material is rebar, which does not have a user-defined stress-strain curve and is specified to use Caltrans default controlling strain values, which are bar size dependent.

Temp (Optional)
Type: SystemDouble
The temperature at which the specified data is to be retrieved. The temperature must have been defined previously for the material.

This item applies only if the specified material has properties that are temperature dependent. That is, it applies only if properties are specified for the material at more than one temperature.

Return Value

Type: Int32
Returns zero if the data is successfully retrieved; otherwise it returns a nonzero value.
