section
('RCSection2d', secTag, coreMatTag, coverMatTag, steelMatTag, d, b, cover_depth, Atop, Abot, Aside, Nfcore, Nfcover, Nfs) 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
(int)unique section tag coreMatTag
(int)tag of uniaxialMaterial assigned to each fiber in the core region coverMatTag
(int)tag of uniaxialMaterial assigned to each fiber in the cover region steelMatTag
(int)tag of uniaxialMaterial assigned to each reinforcing bar d
(float)section depth b
(float)section width cover_depth
(float)cover depth (assumed uniform around perimeter) Atop
(float)area of reinforcing bars in top layer Abot
(float)area of reinforcing bars in bottom layer Aside
(float)area of reinforcing bars on intermediate layers Nfcore
(float)number of fibers through the core depth Nfcover
(float)number of fibers through the cover depth Nfs
(float)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.
