Member Function Documentation

addInitialSectionDeformation()

int XC::SectionForceDeformation::addInitialSectionDeformation ( const Vector &  def )

virtual

Adds to the generalized strains vector inicial el being passed as parameter.

getRho()

double XC::SectionForceDeformation::getRho ( void  ) const

virtual

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

Reimplemented in XC::MembranePlateFiberSection, and XC::ElasticMembranePlateSection.

getSectionFlexibility()

const XC::Matrix & XC::SectionForceDeformation::getSectionFlexibility ( void  ) const

virtual

Returns the tangent flexibility matrix of the section.

Obtains the section tangent stiffness matrix, \(ksec\), and returns its inverse, the section flexibility matrix, \(fsec\), via an explicit matrix inversion. NOTE: The explicit matrix inversion provides default behavior and may be overridden in subclasses to suit specific SectionForceDeformation implementations.

Reimplemented in XC::SectionAggregator, XC::GenericSection1d, XC::ElasticSection2d, XC::ElasticSection3d, XC::YieldSurfaceSection2d, XC::ElasticShearSection3d, XC::FiberSectionShear3d, and XC::ElasticShearSection2d.

getType()

virtual const ResponseId& XC::SectionForceDeformation::getType ( void  ) const

pure virtual

Return the ordering and type of response quantities returned by this object.

Return the section ResponseId code that indicates the ordering and type of response quantities returned by the section. Lets the calling object (e.g. an Element) know how to interpret the quantites returned by this object.

Implemented in XC::SectionAggregator, XC::Isolator2spring, XC::GenericSection1d, XC::Bidirectional, XC::GenericSectionNd, XC::FiberSection2d, XC::ElasticSection2d, XC::ElasticSection3d, XC::FiberSectionGJ, XC::FiberSection3d, XC::FiberSectionShear3d, XC::MembranePlateFiberSection, XC::ElasticShearSection3d, XC::YieldSurfaceSection2d, XC::ElasticShearSection2d, XC::ElasticMembranePlateSection, and XC::ElasticPlateSection.

setTrialSectionDeformation()

virtual int XC::SectionForceDeformation::setTrialSectionDeformation ( const Vector &  )
