Type Standard Bracket, Overall Characteristics

A type standard bracket has the following main characteristics as further developed below.

1. It is in one way or other registered by a name ("bracket designation") by which it is accessed for modelling. The names can in principle be selected arbitrarily.

2. Its geometry is well defined and must follow certain principles: It must be built up by two or three arms. Two arms end in toes that are connected by a free side. Notches may be inserted in all corners and the free side may be supplied with a folded or welded flange. The figure below shows one typical two-arm and one three-arm bracket.

   

   Figure 1:3. Example of one 2-arm and one 3-arm bracket.

3. A bracket may occur in a number of connection cases. Each connection case corresponds to how a bracket in a certain structural arrangement interacts with other structural members. A connection case may have many variants. A certain bracket may occur in several connection cases.

   The connection cases analyzed and supported by the system can be found in Hull Planar Modelling, Design Language of Hull.

   AVEVA Marine evaluates the position and orientation and in many cases also some size parameters from the connected elements.

4. A bracket may or may not be stiffened. The stiffening is produced either via a flange, (bent or welded) or by stiffeners, welded onto the bracket or along its free edge. A bracket may have one flange and/or stiffeners.

5. Brackets cannot be generated with holes but may have cutouts for penetrating profiles.
