An investigation of the fatigue strength of three bulb plate stiffener joints is discussed. In addition to the usual joint with completely welded bulb, two further configurations are considered: one having a weakened bulb and another one having extra reinforcement to compensate for the unwelded bulb. The fatigue life for the usual and for the

Firstly, in terms of plate stiffening, bulb flat bars are a great solution for plate stiffening. Bulb flats provide a low paint area, with no need for edge grinding prior to painting and require fewer lugs compared with alternative plate stiffeners.

Ship Building Steel section. Bulb bars/flats are asymmetrical plate stiffeners used for ship building hull construction (Ship Hull, Ballast Tanks, and Cargo Holds) & Bridges (Box & Plate Girder, Steel Decks, and Expansion Joints). These special profiles provide a wide range of benefits compared to conventional plate stiffeners used for the purpose.
