An improved composite stiffener and methods and tooling used to form the same. The stiffener includes one or more base flanges, a composite rod extending in an axial direction, a bulb cap surrounding the composite rod, and an upright web extending from the one or more base flanges to the base cap. The upright web includes a non-linear profile in the axial direction providing the improved

The Bulb flat is a hot laminated steel product with a bulb in one or both of its edges. We produce bulb flats according to the 3.1.

4. The bulb stiffener of claim 1, wherein the one or more base flanges includes a pair of base flanges. 5. The bulb stiffener of claim 1, wherein the composite rod is comprised of a majority of fibers aligned in the axial direction. 6. The bulb stiffener of claim 5, wherein the upright web and bulb cap are comprised of +/−45-degree fibers.

The use of bulb flat plate stiffeners in ship design is said to reduce building time and maintenance cost. Companies that produce bulb flat plate stiffeners manufacture each stiffener as a single unit, which reportedly results in less production cost compared to welded or fabricated stiffeners.

The bulb plates are the plate stiffener of choice for the shipbuilding industry due to their excellent strength to weight ratio. They feature a

Bulb flats are tailor made for plate stiffening applications. Their special shape provides significant benefits compared with other types of stiffener.

Because of the rounded edges, Bulb Flats are excellent stiffeners with a longer life span compared to angles in terms of corrosion-resistance and 

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.

2 Buckling Capacity of Plates and Stiffeners. 2.1 Overall stiffened panel capacity. 2.1.1 The elastic stiffened panel limit state is based on the following interaction formula: where cf and Pz are defined in [2.3.4]. 2.2 Plate capacity. 2.2.1 Plate limit state The plate limit state is based on the following interaction formulae:

with other stiffeners such as flat bars or structural angles. • The compact shape of a bulb flat offers easy access for welding and painting. • The asymmetric bulb flat shape lends itself to simplified collar connection when compared to alternative stiffeners such as 'T's and angles. • The rounded profile of a bulb flat,

with bulb-flanges can be used instead of other harder-to-produce and assemble sections like Hat- or Tee-stiffeners which have served the industry favorably for decades. Figure 1 illustrates the general cross-section of a bulb-flange as opposed to a regular Tee and I cross-section. Asymmetric bulb-flanges are preferred for the following reasons.

Jun 25,  · Bulb stiffeners are basic structural elements and widely used in ships and offshore platforms. Large amount of bulb stiffeners constitute the main frames of those engineering structures and help them to withstand complicated and harsh environmental loadings.

This paper presents a practical method for designing bulb-flat-stiffened plating against local buckling, without limitations on section slenderness. The aim is to improve the current shape limitation requirements of BS 5400: Part 3, which are known to be unduly conservative.
