simdesign.rcmrf.bdim.tr_0018_dcm.column

This module provides the column class implementation for the tr_0018_dcm design class in the BDIM layer.

simdesign.rcmrf.bdim.tr_0018_dcm.column.ECONOMIC_MU: float = 0.25: Maximum mu value considered for the economic column design.

simdesign.rcmrf.bdim.tr_0018_dcm.column.MAX_NIU = 0.5: Maximum allowed value of axial load ratio. Based on Section 7.3 in TBEC-1998 and Section 3.3 in TBEC-2007.

class simdesign.rcmrf.bdim.tr_0018_dcm.column.Column(line, section, gamma_rc)[source]

Bases: ColumnBase

Column implementation for design class tr_0018_dcm.

This class extends ColumnBase by narrowing the attribute types and overriding design methods per TBEC-2007 and TS500-2000.

Variables:

steel (Steel) – Steel material assigned to the column.
concrete (Concrete) – Concrete material assigned to the column.
MIN_B_SQUARE (float) – The default minimum square column dimension.
MIN_B_RECTANGLE (float) – The default minimum rectangular column dimension.

Parameters:

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