4.15.7. RCCircular Section

section('RCCircularSection', secTag, coreMatTag, coverMatTag, steelMatTag, d, cover_depth, As, NringsCore, NringsCover, Newedges, Nsteel, '-GJ', GJ)

This command allows the user to construct an RCCircularSection object, which is an encapsulated fiber representation of a circular reinforced concrete section with core and confined regions of concrete.

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 radius
cover_depth (float)	cover depth (assumed uniform around perimeter)
As (float)	area of reinforcing bars
NringsCore (int)	number of fibers through the core depth
NringsCover (int)	number of fibers through the cover depth
Newedges (int)	number of fibers through the edges
Nsteel (int)	number of fibers through the steels
GJ (float)	GJ stiffness

Note

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