VEW2 ‘Channel’ Windposts
Verified by manufacturer 23 days ago
BS EN 1090 EXC2
Certificate type
Channel windposts.
Application
Both the VEW1 and VEW2 type windposts span vertically between floors and the design will usually include a positively fixed base and a top fixing that will allow differential movement between the structure and the masonry.
Description
The VEW2 range of windposts are of channel section where the post sits in the cavity of the wall, they are generally used for lighter load conditions than the VEW1 type posts. The use of a VEW2 Windpost is governed by the size of the cavity and the load to be supported i.e. it may not be possible to increase the section of the post and therefore its load capacity due to the size of the cavity.
The windposts are usually designed as ‘simply supported beams’ with a maximum allowable deflection of span/360 and a maximum allowable design stress of 193.75 N/mm² (includes +25% allowance for transient windload).
Where deflection is the limiting factor windposts may be designed as a ‘propped cantilever’, using this method reduces the deflection of the windpost considerably but requires a much larger baseplate.
The WPTC one way tie is clipped to VEW2 edges to tie into both block and brick courses.
