pystra.options.SORMOptions#

class SORMOptions(*, fit='curve', formula='breitung', ffd_parameter=1000, form=FORMOptions())[source]#

Bases: object

Settings for SORM.

Parameters:

  • fit (str) – Curve fitting through the Hessian at the design point, or point fitting on the limit-state surface.

  • formula (str) – The approximation reported as the estimate; both are computed.

  • ffd_parameter (float) – Finite-difference step divisor for the Hessian: the step in standard coordinates is its reciprocal.

  • form (FORMOptions) – Settings of the FORM analysis that SORM runs when none is supplied. A supplied FORM analysis keeps its own settings.
