Stiffener Statement

The STIFFENER statement generates stiffeners on panels and swedging.

Stiffeners are all stored in exactly the same way, if they are small connection stiffeners or if they are big profiles on bulkheads or decks. However, since stiffeners occur in so many different kinds of structures, it may be convenient to generate them according to somewhat different combinations of input. This means that input can be given according to different syntaxes. The syntaxes for connection stiffeners and curved stiffeners are so different from the others that they will be treated quite independently.

The different sub-syntaxes are:

1. "Mold line first" - the mold line of the stiffener is defined first and when this is done,the end points are calculated, using the mold line.

2. "End point first" - the end points are defined directly, for instance via connections to an intersecting longitudinal.
   A special case of this is when one end point defines the end point as well as the direction of the stiffener.

3. "Connection stiffeners" - this syntax is characterized by a high degree of automation, that means, very little input has to be given.

4. Syntax for curved stiffeners.
