Bases:
StrandProfile
Class for a PCI Strand (1992).
Class for a strand stress-strain profile by R. Devalapura and M. Tadros from the March-April issue of the PCI Journal.
- Parameters:
yield_strength (float) – Strand yield strength
elastic_modulus (float) – Strand elastic modulus
fracture_strain (float) – Strand fracture strain
breaking_strength (float) – Strand breaking strength
bilinear_yield_ratio (float) – Ratio between the stress at the intersection of a bilinear profile, and the yield strength
strain_cps (list[float]) – Strain control points, generates the following strain segments:
[0, strain_cps[0], strain_cps[1], fracture_strain]
. Length must be equal to 2.n_points (list[int]) – Number of points to discretise within each strain segment. Length must be equal to 3.
