The calculation of the load-bearing capacity of ship plates

TAGS: ship | plates | loadbearing |

Ship plates are an essential material for constructing ships. The load-bearing capacity of ship plates is a critical consideration during the design process. The load-bearing capacity of a plate depends on its material, thickness, and shape, as well as the load it carries. In the context of shipbuilding, the primary load-bearing capacity that needs to be considered is the longitudinal bending strength.

The longitudinal bending strength of the ship plate is the resistance to the bending stress that occurs along the length of the plate under the weight of the ship's cargo and its own weight. The bending stress leads to the formation of tensile and compressive stresses in the plate. The ship plates should be thick enough to bear the compressive and tensile stresses induced by the bending forces.

The load-bearing capacity of ship plates is calculated through the following formula:

P = 0.7 x σb x t x b

Where P is the load-bearing capacity in tons, σb is the allowable stress, t is the thickness in millimeters, and b is the breadth of the plate in meters.

The allowable stress of a ship plate depends on its material and the class of the ship. The International Association of Classification Societies (IACS) sets standards for classifying ships based on their design, construction, and operation. The allowable stresses for different grades of steel plates are specified in the IACS classification rules.

calculating the load-bearing capacity of ship plates requires a thorough understanding of the plate's material, thickness, and shape, as well as the load it carries. The calculation of the longitudinal bending strength is critical for ensuring the safety and stability of the ship. It is essential to adhere to the IACS classification rules to ensure that the ship plates used in construction meet the required load-bearing capacity standards.
