This command allows the user to construct an RCSection2d object, which is an encapsulated fiber representation of a rectangular reinforced concrete section with core and confined regions of concrete and single top and bottom layers of reinforcement appropriate for plane frame analysis.

$secTag unique section tag
$coreTag tag of uniaxialMaterial assigned to each fiber in the core region
$coverTag tag of uniaxialMaterial assigned to each fiber in the cover region
$steelTag tag of uniaxialMaterial assigned to each reinforcing bar
$d section depth
$b section width
$cover cover depth (assumed uniform around perimeter)
$Atop area of reinforcing bars in top layer
$Abot area of reinforcing bars in bottom layer
$Aside area of reinforcing bars on intermediate layers
$Nfcore number of fibers through the core depth
$Nfcover number of fibers through the cover depth
$Nfs number of bars on the top and bottom rows of reinforcement (Nfs-2 bars will be placed on the side rows)


For more general reinforced concrete section definitions, use the Fiber Section command.
