m_n_kappa.UPEProfile#

class m_n_kappa.UPEProfile(top_edge, t_f, b_f, t_w, h_w=None, h=None, centroid_y=0.0)#

Bases: ComposedGeometry

UPE-Profile composed of class Rectangles forming a reversed U

New in version 0.1.0.

Parameters:

  • top_edge (float) – top-edge of the rectangle \(z_\mathrm{top}\)

  • t_f (float) – flange-thickness \(t_\mathrm{f}\)

  • b_f (float) – flange-width \(b_\mathrm{f}\)

  • t_w (float) – web-thickness \(t_\mathrm{w}\)

  • h_w (float = None) – web-height \(h_\mathrm{w}\) (Default: None). Alternative argument h must be given, otherwise an exception will be risen.

  • h (float = None) – overall height of the steel-profile \(h\) (Default: None). Alternative arguments h_w and t_f must be given.

  • centroid_y (floats) – horizontal position of the centroid of the UPE-profile \(y_\mathrm{centroid}\) (Default: 0.0)

Example

The following example creates Rectangle instances forming an UPE 200 profile

>>> from m_n_kappa import UPEProfile
>>> upe200_geometry = UPEProfile(top_edge=10, t_f=5.2, b_f=76, t_w=9.0, h=200)
>>> upe200_geometry
UPEProfile(top_edge=10, t_f=5.2, b_f=76, t_w=9.0, h_w=189.6, h=200, centroid_y=0.0, geometries=[Rectangle(top_edge=10.00, bottom_edge=86.00, width=5.20, left_edge=-100.00, right_edge=-94.80), Rectangle(top_edge=10.00, bottom_edge=19.00, width=189.60, left_edge=-94.80, right_edge=94.80), Rectangle(top_edge=10.00, bottom_edge=86.00, width=5.20, left_edge=94.80, right_edge=100.00)])

As UPEProfile inherits from ComposedGeometry it also inherits its functionality tranforming to a m_n_kappa.Crosssection by adding m_n_kappa.Material.

>>> from m_n_kappa import Steel
>>> steel = Steel(f_y = 300.0, f_u = 350.0, failure_strain=0.25)
>>> cross_section = upe200_geometry + steel
>>> cross_section
Crosssection(sections=sections)
