Design and verification of pin connection as per Eurocode

The spreadsheet verifies a connection composed by plates jointed with pins. The verification is performed taking into account the Eurocode norm EN 1993-1-8:2005 § 3.13 Tab. 3.10.

Different cases are covered by the spreadsheet:

  • Connection composed by 3 plates in a standard pin configuration
  • Connection composed by 2 plates
  • Connection composed by 4 plates equally spaced.
  • Verification of one single plate with pin. It allows to verify the pin connection inserting directly the forces on the pin section (shear and bending).


  • Four different configurations for the pin connection
  • Pin shear resistance
  • Pin bending resistance
  • Pin combined shear and bending resistance
  • Plate bearing resistance
  • Ultimate Limit State
  • Serviceability Limit State (replacement of the pin)
  • Reaction forces on the connection plates
  • Verification of the geometry of the lug and minimum distances check as per Eurocode
  • User materials for yielding and ultimate strenght

    In the pin connection with 3 plates, Fsd = 2* should be use in the bending moment formular?
