Lifting Lug Calculations

(0/0)

Description

The Eurocode provides methods for assessing lug strength, while ESDU (Engineering Sciences Data Unit) offers an alternative approach. Here’s a brief comparison:

  1. Eurocode Method:

    • Ultimate Resistance of Net Cross-Section: This considers the maximum load a lug can withstand before failure.
    • Deductions for Fastener Hole: Adjustments are made to account for holes where fasteners (bolts or rivets) pass through the lug.
    • Design Resistance of Individual Fasteners: Evaluates the strength of each fastener.
    • Lifting Lug Allowables and Margin of Safety: Determines safe working loads and incorporates a safety margin.
  2. ESDU Method:

    • Axial Rupture: Calculates the minimum load causing rupture (failure) of the lug under axial loading.
    • Axial Shear Bearing: Assesses shear-bearing failure under axial loads.
    • Axial Permanent Deformation: Determines the maximum permissible permanent deformation.
    • Transversal Rupture: Considers rupture due to transverse loads.
    • Transversal Permanent Deformation: Evaluates permanent deformation under transverse loads.
    • Bearing Permanent Deformation: Addresses permanent deformation due to bearing loads.

    Additionally, ESDU accounts for effects like pin bending in double shear joints.
