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.
