class simdesign.rcmrf.bdim.eu_cdm.beam.Beam(line, typology, gamma_rc)[source]

Bases: BeamBase

Beam implementation for design class eu_cdm.

This class extends BeamBase by narrowing the attribute types and overriding design methods per REBAP (1983).

Variables:

  • steel (Steel) – Steel material assigned to the beam.

  • concrete (Concrete) – Concrete material assigned to the beam.

  • MIN_B_EB (float : float) – The default minimum breadth (width) of emergent beams.

Parameters:

  • line (Line)

  • typology (Literal[1, 2])

  • gamma_rc (float)

Notes

  • Top reinforcement is calculated as the maximum of required reinforcement in tension for maximum of negative bending moments and required reinforcement in compression for maximum of positive bending moments.

  • Bottom reinforcement is calculated as the maximum of required reinforcement in compression for maximum of negative bending moments and required reinforcement in tension for maximum of positive bending moments.

  • Required reinforcement is computed at three different sections: start, middle, end.

Return type:

None
