Introduction
Parapet and spandrel posts are designed as cantilevers and are available in both the GA VEW1 and GA VEW2 section types.
Larger base connections will be required to resist the ‘bending moment’ and careful consideration of the plate, fixings and base structure is required to ensure the post resists the applied loading
GA VEW1 Parapet Post Properties
The table below shows section properties, recommended resistance loads and design resistance loads for VEW1 Parapet Posts designed as cantilevers.
For further information on alternative GA VEW1 Parapet Post sections and loadings, please contact GA.
GA VEW2 Parapet Post Properties
The tables also contain section properties, recommended load and design load figures for VEW2 Parapet Post sections when used as cantilevers.
For further information on alternative GA VEW2 Parapet Post sections and loadings, please contact GA.
Base plate examples
Example 1
Base fixed using Expansion Anchors into concrete slab.
Example 2
Base fixed using M12 Isolated Setscrews into steelwork.
Example 3
Base fixed using Expansion Anchors into concrete slab.
Performance Tables
Windposts are designed as simply supported beams with a maximum design strength of 230N/mm2 and a maximum deflection of span/360. Design resistances should be compared with factored loads. Recommended loads include a variance factor of 1.5
