simdesign.rcmrf.bdim.eu_cdh.building

This module provides the Building Design Information Model (BDIM) implementation for the eu_cdh design class.

class simdesign.rcmrf.bdim.eu_cdh.building.Building(taxonomy)

Bases: BuildingBase

BDIM implementation for design class eu_cdh.

This class extends BuildingBase by narrowing the attribute types to the eu_cdh implementations and overriding design class-specific methods.

Parameters:

Type:

List[Column]

joints

List of joint instances.

Type:

List[Joint]

slabs

List of slab instances.

Type:

List[Slab]

stairs

List of stairs instances.

Type:

List[Stairs]

infills

List of infill wall instances.

Type:

List[Infill]

steel

Steel material instance used in the design of beams and columns.

Type:

Rebars

quality

Quality instance used to adjust properties of structural elements.

Type:

OVERSTRENGTH_FACTOR_COLUMN_MOMENT

Safety or overstrength factor considered in calculation of capacity design moments for columns (strong-column weak-beam principle). The default value is 1.3, see EN 1998-1:2004 4.4.2.3(4).

Type:

float | None

OVERSTRENGTH_FACTOR_BEAM_SHEAR

Safety or overstrength factor considered in calculation of capacity design shear forces for beams. Overstrength factor for DCM is considered here. - 1.0 for DCM beams, see EN 1998-1:2004 clause 5.4.2.2(2) - 1.2 for DCH beams, see EN 1998-1:2004 clause 5.5.2.1(3)

Type:

float | None

OVERSTRENGTH_FACTOR_COLUMN_SHEAR

Safety or overstrength factor considered in calculation of capacity design shear forces for columns. Overstrength factor for DCM is considered here. - 1.1 for DCM columns, see EN 1998-1:2004 5.4.2.3(2) - 1.3 for DCH columns, see EN 1998-1:2004 5.5.2.2(3)

Type:

float | None

Base class defining the core behaviour and configuration.

Notes

• Design follows limit state design approach.

• Capacity design principle is followed (weak-beam strong-column).

• Main reference building code is Eurocode 8-1 (moderate ductility class).

• Material strengths are higher compared to ‘eu_cdm’.

• Basic units are kN, m, sec

• Overrides _set_maximum_column_dimensions() method to set design-class specific maximum column dimensions.

• Overrides _change_materials() method to use design-class specific material change order.
