Introduction

VEW3 Spine Posts add strength and stability to single leaf walls without protruding beyond the width of the blockwork. In this way, decorative wall surfaces and ‘fair faced’ finishes are possible without compromising on safety. Although the width of VEW3 Spine Posts is limited by the width of the masonry (we recommend they sit within the wall by at least 10mm either side), the thickness of the post itself can be increased to add to its load capacity.

GA VEW3 Spine Post Properties

The tables below show section properties, recommended resistance loads and design resistance loads for VEW3 Spine Posts acting as simply supported beams. For further information on alternative VEW3 Spine Post sections and loadings for posts designed as propped cantilevers, please contact GA.

 

 

GA WPT2

Spine posts are tied in using GA WPT2 ties. These are usually supplied 200mm long and can be ordered with a debonding sleeve for spine posts being used at movement joint locations.

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
