simdesign.rcmrf.bdim.eu_cdm.beam

This module provides the beam class implementation for the eu_cdm design class in the BDIM layer.

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).

Parameters:

line (Line)
typology (Literal[1, 2])
gamma_rc (float)

steel

Steel material assigned to the beam.

Type:: Steel

concrete

Concrete material assigned to the beam.

Type:: Concrete

MIN_B_EB

The default minimum breadth (width) of emergent beams.

Type:: float : float

property rhol_min_tens: float

Returns:: Minimum longitudinal reinforcement ratio in tension zone.
Return type:: float

property rhol_max_tens: float

Returns:: Maximum longitudinal reinforcement ratio in tension and compression zones.
Return type:: float

property rhoh_min: float

Returns:: Minimum transverse reinforcement ratio.
Return type:: float

verify_section_adequacy()[source]

Verify the beam section dimensions for design forces.

Return type:: None

compute_required_longitudinal_reinforcement()[source]

Compute the required longitudinal reinforcement for design forces.

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

compute_required_transverse_reinforcement()[source]

Compute the required transverse reinforcement for design forces.

Notes

Reinforcement is computed at three sections: start, mid, and end.

Return type:: None
