◆ getResponseType()

const XC::ResponseId & XC::ElasticSection1d::getResponseType ( void  ) const
virtual

Section stiffness contribution response identifiers.

Returns the section ID code that indicates the ordering of section response quantities. For this section, axial response is the first quantity, bending about the local z-axis is the second, and shear along the local y-axis is third.

\[ //! code := \left[ //! \begin{array}{c} //! 2 //! \end{array} //! \right] //! \]

Implements XC::SectionForceDeformation.

◆ getSectionFlexibility()

const XC::Matrix & XC::ElasticSection1d::getSectionFlexibility ( void  ) const
virtual

Returns the flexibility matrix.

\[ fsec = \left[ \begin{array}{c} \frac{1}{EA} \end{array} \right] \]

Reimplemented from XC::SectionForceDeformation.

◆ getSectionTangent()

const XC::Matrix & XC::ElasticSection1d::getSectionTangent ( void  ) const
virtual

Returns the tangent stiffness matrix.

\[ fsec = \left[ \begin{array}{c} EA \end{array} \right] \]

Implements XC::SectionForceDeformation.

◆ getStressResultant()

const XC::Vector & XC::ElasticSection1d::getStressResultant ( void  ) const
virtual

Returns the cross-section stress resultant.

Returns the section stress resultants, \(ssec\), the product of the section stiffness matrix, \(ksec\), and the section deformation vector, \(esec\),

\[ ssec = ksec esec = \left[ \begin{array}{c} P \end{array} \right] \]

where \(P\) is the axial force, \(M_z\) is the bending moment about the local z-axis, and \(V_y\) is the shear force along the local y-axis.

Implements XC::SectionForceDeformation.
