Ductility

  • The reinforcement type (as defined in the design section or design strip segment) is considered (PT or RC).
  • The longitudinal reinforcement from all other designs (except other ductility) is considered to be in place before ductility reinforcement is added.
  • The bending moments sign (or signs) is determined by the moment envelope for the rule set layer (ductility could be required for both positive and negative moments).
  • Code Rules are applied as shown in the following table.
