What Is a Deck Beam?

Upper deck beam refers to the beam that carries the upper deck ribs. The upper deck refers to the power deck, the upper continuous deck of the ship, that is, the highest full deck. ^[1] The deck beams installed on the deck use the same principle as the general ribs, using section steel. This is a combination of a triangular plate and a rib called a beam axillary plate, which has great strength for the lateral deformation of the hull. ^[2]

In addition to supporting the upper deck weight, the pillars provided to support the beams between the deck and the deck are connected to the ship's bottom deck to maintain the transverse shape of the hull and give the hull rigidity and prevent vibration.

Supporting deck beams in principle uses pillars, but erecting the pillars increases the inconvenience of loading and unloading cargo. A longitudinal beam under the beam is set up, and only one pillar is set for several ribs. A deck longitudinal beam is set under the deck, and a wide distance The column supports the beam. ^[2]
