compute_average_edge_stiffness

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

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.

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

  • Ah (float) – 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

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