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.

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)
