simdesign.rcmrf.bdim.baselib.analysis

This module provides the base class implementation for the elastic numerical model used in the BDIM layer.

class simdesign.rcmrf.bdim.baselib.analysis.ElasticModelBase(beams, columns, loads, geometry, beta)

Bases: ABC

Abstract base class for the elastic model builder in the BDIM layer.

Provides common OpenSees model building logic shared across all design classes. Must be inherited by design-class-specific elastic model implementations.

Variables:

• beams (List[BeamBase]) – Beam objects of the building.

• columns (List[ColumnBase]) – Column objects of the building.

• geometry (GeometryBase) – General building geometry (elastic frame geometry).

• loads (LoadsBase) – Loads instance for the current design class.

• beta (float) – Design lateral load factor (in g).

Parameters:

• beams (List[BeamBase])

• columns (List[ColumnBase])

• loads (LoadsBase)

• geometry (GeometryBase)

• beta (float)

beams: List[BeamBase]

columns: List[ColumnBase]

geometry: GeometryBase

loads: LoadsBase

beta: float

analyze_for_all()

Analyze the building and store element forces for all load cases and combinations.
