Ancon Shearfix

Ancon Shearfix is designed to suit the specific requirements of each application.

The Ancon design program simplifies the specification and ordering of a Shearfix System. This easy-to-use program allows the optimum design to be determined and generates a printable calculation sheet, a DXF file and a parts list of the specified layout. The program allows analysis to BS EN 1992 (Eurocode 2).

Solutions can be created for a wide range of column sizes, shapes and locations including columns offset from edges and corners.

Where there are openings close to the column, a section of the slab will be ineffective and perimeters will need to be reduced; the Ancon design program allows these reductions to be applied to each perimeter. 

The design program requires the following information and is requested in a logical sequence as the user works through the 'input' tabs:

  • Column shape (circular, rectangular or ‘L’ shape)
  • Column dimensions
  • Column location (interior, edge, external corner, re-entrant corner, wall corner, wall end)
  • Dimension to concrete edge (for offset corner and edge columns)
  • Slab thickness
  • Concrete grade
  • Reinforcement size and spacing
  • Cover to reinforcement
  • Size and location of slab openings
  • Shear load
  • Applied moments
