===========================
Elastic Beam Column Element
===========================

This command is used to construct an elasticBeamColumn element object. The arguments for the construction of an elastic beam-column element depend on the dimension of the problem, (ndm)



.. function:: element('elasticBeamColumn', eleTag, *eleNodes, Area, E_mod, Iz, transfTag, <'-mass', mass>,<'-cMass'>, <'-release', releaseCode>)
   :noindex:
   
   
.. function:: element('elasticBeamColumn', eleTag, *eleNodes, secTag, transfTag, <'-mass', mass>,<'-cMass'>, <'-release', releaseCode>)
   :noindex:

   For a two-dimensional problem


.. function:: element('elasticBeamColumn', eleTag, *eleNodes, Area, E_mod, G_mod, Jxx, Iy, Iz, transfTag, <'-mass', mass>, <'-cMass'>)
   :noindex:
   
.. function:: element('elasticBeamColumn', eleTag, *eleNodes, secTag, transfTag, <'-mass', mass>, <'-cMass'> <'-releasez', releaseCode>, <'-releasey', releaseCode>)
   :noindex:   

   For a three-dimensional problem
