Barrier Post Design Workbook V3

Spreadsheet for design of barrier post: version 3. Simple spreadsheet which calculates the base moment for a post supporting a guardrail or other barrier (eg. glass balustrade). From the design moment a structural section is looked up from a customisable table of section resistances (phi.Ms).


  1. Posts typically require 100mm to 150mm embedment when cast-in to a floor slab, whilst anchor bolts typically require a minimum  of 70mm to 100mm.
  2. A post fastened to a fascia beam will place torsion in such beam.
