Brackets

The geometry and other information of a bracket are found either from the bracket contour of the panel object or from a separate bracket object.

The outer contour of the bracket contains the cutouts and notches. Its area and moments are subtracted by the area and moments of the holes. The moments divided by area give the mass center of the bracket in its own plane coordinate system.

The mass center is then moved to the center of plate thickness in w-direction and transformed to the ship coordinate system.

If the bracket contains stiffeners, their weight results are obtained in the same way as those of the straight stiffeners.

The weight of panel brackets is calculated as for panels.
