Stiffening

The free edge of the bracket may be stiffened in three different ways:

1. By a folded flange (see above)

2. By a welded flange (face plate), either welded symmetrically (forming a symmetrical T section) or asymmetrically (forming an asymmetric T section). This flange may either be straight or curved depending on the shape of the free edge of the bracket.

3. By a stiffener, welded parallel to the free edge (or part thereof) at a specified distance. This stiffener may be double, that means, occur on both sides of the bracket.

   In addition it is possible to specify at most four additional stiffeners in the interior of a bracket, all set parallel to the free edge. Options are available to control the number of stiffeners as a function of the size of the bracket and to control their position and dimensions in a similar way.

   When calculating the end points of a bracket stiffener the specified distance is by default calculated between the edge and the closest point of the stiffener (=d1). By adding the default parameter BKT_OLDPROF to the default file of Hull Modelling the distance will be calculated to the closest end point on the mould line instead (=d2), see the figure below.
