.ConcreteTensionStiffening

Required argument

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

rate

A Boolean specifying whether the data depend on rate. The default value is OFF.

type

A SymbolicConstant specifying the type of postcracking behavior data. Possible values are:

  • STRAIN, specifying postfailure stress as a function of cracking strain.

  • DISPLACEMENT, specifying postfailure stress as a function of cracking displacement.

  • GFI, specifying failure stress as a function of the fracture energy.

The default value is STRAIN.

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

Table data

If type=STRAIN, the table data specify the following:

  • Remaining direct stress after cracking, .

  • Direct cracking strain, .

  • Direct cracking strain rate, .

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

If type=DISPLACEMENT, the table data specify the following:

  • Remaining direct stress after cracking, .

  • Direct cracking displacement, .

  • Direct cracking displacement rate, .

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

If type=GFI, the table data specify the following:

  • Failure stress, .

  • Fracture energy, .

  • Direct cracking displacement rate, .

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

Return value

A ConcreteTensionStiffening object.

Exceptions

RangeError.


29.23.2 setValues(...)
