.. _RCSection:

RCSection
^^^^^^^^^

This command constructs a reinforced-concrete rectangular section by discretizing the cross section into fibers. The command name in OpenSees is ``RCSection2d``.

.. function:: section RCSection2d $secTag $coreTag $coverTag $steelTag $h $b $cover $Atop $Abottom $Aside $nfcore $nfcover $nfs

.. csv-table::
   :header: "Argument", "Type", "Description"
   :widths: 10, 10, 40

   $secTag, |integer|, unique section tag
   $coreTag, |integer|, uniaxial material tag for the concrete core
   $coverTag, |integer|, uniaxial material tag for the concrete cover
   $steelTag, |integer|, uniaxial material tag for the longitudinal reinforcement
   $h, |float|, section depth
   $b, |float|, section width
   $cover, |float|, concrete cover thickness
   $Atop, |float|, total area of top reinforcement steel
   $Abottom, |float|, total area of bottom reinforcement steel
   $Aside, |float|, total area of side reinforcement steel
   $nfcore, |integer|, number of fibers in the core
   $nfcover, |integer|, number of fibers in each cover region
   $nfs, |integer|, number of fibers used to discretize each steel layer
