10.8 Beam reinforcement

$\rightarrow $ https:://concrete-fem.com

A section starting with *BEAM REINF defines the geometry of reinforcement layers. It is used in connection with a beam section.

The section keyword *BEAM REINF has as option


specifies a unique name which basically may be freely chosen

The following data lines describe a reinforcement layer with the following geometric properties



$\varrho _{eff}$,

$\beta _t$



cross section area


height coordinate with respect to the reference line ($z_s<0$ downward, $z_s>0$ upward)


(reference line goes through the cross section center in case of *SECTION=RECT)

$\varrho _{eff}$

effective reinforcement ratio (used only for tension stiffening)

$\beta _t$

bond parameter ($\beta =0$: no tension stiffening)

The reinforcement material properties are defined with the material type *RCBEAM. Further data lines may follow for further reinforcement layers if required. The number of reinforcement layers is not restricted.

The section keyword *BEAM REINF has no own sub-keywords.
