pycba.foundation.FoundationElement#

class FoundationElement(L, EI, kf, n=None)[source]#

Bases: object

Beam-on-elastic-foundation super-element for one prismatic member.

Parameters:

  • L (float) – Member length.

  • EI (float) – Flexural rigidity (prismatic; a SectionEI raises NotImplementedError).

  • kf (float) – Winkler foundation modulus (modulus of subgrade reaction per unit beam length: force / length / length).

  • n (Optional[int]) – Number of internal sub-elements. Defaults to auto_subdivisions().

Methods

recover

Member load-effect arrays along the member given its end displacements dr = [v_i, θ_i, v_j, θ_j] (from the global solve) and its loads.

ref

Condensed two-node fixed-end reactions (PyCBA get_ref convention).
ref(loads)[source]#

Condensed two-node fixed-end reactions (PyCBA get_ref convention).

Return type:

ndarray

recover(dr, loads, npts)[source]#

Member load-effect arrays along the member given its end displacements dr = [v_i, θ_i, v_j, θ_j] (from the global solve) and its loads.

Return type:
