compute_average_edge_stiffness

compas_tno.utilities.compute_average_edge_stiffness(form, E=20000000.0, Ah=0.001)

Compute the stiffness divided by length of each edge (constant thoughout the form diagram) based on the Young Modulus E and the Axial stress Ah.

Parameters:

form::FormDiagram::

Form diagram to compute the stiffness.

Efloat

The young modulus of the material. The default value is 20E+6 which corresponds to a 20 GPa commonly used for concrete.

Ahfloat

The axial stress which is assumed to be constant throughout the edges. The default value is 10E-4 which corresponts to a compressive stress of 10 MPa in the section.

Returns:

kfloat

The stiffness divided by length on the edges (constant).
