clt_rectangular_section

sectionproperties.pre.library.timber_sections.clt_rectangular_section(d: list[float], layer_mat: list[Material], b: float) → CompoundGeometry

Constructs a CLT rectangular section.

Constructs a CLT rectangular section, with layer depths d, layer materials layer_mat, and width b.

Parameters:

• d (list[float]) – CLT layer section thickness

• layer_mat (list[Material]) – A list of timber materials for each layer (from top to bottom)

• b (float) – CLT section width

Returns:

CLT rectangular section geometry

Return type:

CompoundGeometry

Example

The following example creates a 120mm CLT cross-section:

from sectionproperties.pre import Material
from sectionproperties.pre.library import clt_rectangular_section
from sectionproperties.analysis import Section

timber0 = Material(
    name="Timber0",
    elastic_modulus=9.5e3,
    poissons_ratio=0.35,
    density=4.4e-7,
    yield_strength=5.5,
    color="burlywood",
)
timber90 = Material(
    name="Timber90",
    elastic_modulus=317,
    poissons_ratio=0.35,
    density=4.4e-7,
    yield_strength=5.5,
    color="orange",
)

geom = clt_rectangular_section(
    d=[40, 40, 40],
    layer_mat=[timber0, timber90, timber0],
    b=1000
)

geom.create_mesh(mesh_sizes=[0])  # a size of zero creates a coarse mesh
Section(geometry=geom).plot_mesh()
