Constructor & Destructor Documentation

◆ BaseElasticSection()

XC::BaseElasticSection::BaseElasticSection ( int  tag,
int  classTag,
const size_t &  dim,
MaterialHandler mat_ldr = nullptr 
)

Constructor.

Parameters
tagidentifier for the object.
classTagidentifier for the object class.
dimdimension (2 or 3).
mat_ldrmanager of the material objects.

Member Function Documentation

◆ getRho()

virtual double XC::BaseElasticSection::getRho ( void  ) const
pure virtual

Returns the density (mass per unit length/area/volume) of the section.

Reimplemented from XC::SectionForceDeformation.

Implemented in XC::BaseElasticSection3d, XC::BaseElasticSection1d, and XC::BaseElasticSection2d.

◆ setTrialSectionDeformation()

int XC::BaseElasticSection::setTrialSectionDeformation ( const Vector def)
virtual

Set the trial (generalized) deformation of the section.

Sets the value of the section deformation vector, \(esec\) to be {def}. The section deformation vector, \(esec\), is defined by

\[ esec := \left[ \begin{array}{c} \epsilon_a\\ \kappa_z\\ \gamma_y \end{array} \right] \]

where \(\epsilon_a\) is the axial strain, \(\kappa_z\) is the curvature about the local z-axis, and \(\gamma_y\) is the shear strain along the local y-axis.

Implements XC::SectionForceDeformation.
