4.16.6. RC Section¶
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.
unique section tag
tag of uniaxialMaterial assigned to each fiber in the core region
tag of uniaxialMaterial assigned to each fiber in the cover region
tag of uniaxialMaterial assigned to each reinforcing bar
cover depth (assumed uniform around perimeter)
area of reinforcing bars in top layer
area of reinforcing bars in bottom layer
area of reinforcing bars on intermediate layers
number of fibers through the core depth
number of fibers through the cover depth
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.
