simdesign.rcmrf.bdim.tr_0018_dch.materials

This module provides the class implementations representing materials for the tr_0018_dch design class in the BDIM layer.

class simdesign.rcmrf.bdim.tr_0018_dch.materials.Steel(*, grade, fsyk, fsyd=None, fsym=None, Es=None, PARTIAL_FACTOR=1.15)[source]

Bases: SteelBase

Steel model implementation for design class tr_0018_dch.

This class extends SteelBase by overriding partial factor attribute.

Variables:

PARTIAL_FACTOR (float) – Partial factor for steel, by default 1.15.

Parameters:

  • grade (str)

  • fsyk (float)

  • fsyd (float | None)

  • fsym (float | None)

  • Es (float | None)

  • PARTIAL_FACTOR (float)

class simdesign.rcmrf.bdim.tr_0018_dch.materials.Materials[source]

Bases: MaterialsBase

Materials implementation for design class tr_0018_dch.

This class extends MaterialsBase by narrowing the attribute types and exposing public accessors for retrieving concrete and steel material instances by grade.

Variables:

  • concrete (List[Concrete]) – List of concrete material instances.

  • steel (List[Steel]) – List of steel material instances.

  • _data_path (Path) – Path to the JSON file containing material data.
