3.1.7.4. RCSection

This command constructs a reinforced-concrete rectangular section by discretizing the cross section into fibers. The command name in OpenSees is RCSection2d.

section RCSection2d $secTag $coreTag $coverTag $steelTag $h $b $cover $Atop $Abottom $Aside $nfcore $nfcover $nfs

Argument	Type	Description
$secTag	integer	unique section tag
$coreTag	integer	uniaxial material tag for the concrete core
$coverTag	integer	uniaxial material tag for the concrete cover
$steelTag	integer	uniaxial material tag for the longitudinal reinforcement
$h	float	section depth
$b	float	section width
$cover	float	concrete cover thickness
$Atop	float	total area of top reinforcement steel
$Abottom	float	total area of bottom reinforcement steel
$Aside	float	total area of side reinforcement steel
$nfcore	integer	number of fibers in the core
$nfcover	integer	number of fibers in each cover region
$nfs	integer	number of fibers used to discretize each steel layer
