Roof Trusses for a pole building

Recommended Posts

Using Chief X8.   Designing a 86' wide pole building.  The trusses on the framing view does not show the webbing, only the top and bottom chord.

On the end truss the framing does show the vertical framing.  How can I get the webbing to show on the 86' wide trusses.  This is my first venture in doing a building this wide. 

Never was a problem on narrower buildings.

I am not sure how it would make a difference on a larger truss but check your Top and Bottom Chord Spans.

It is not totally out of the question.  My supplier can deliver a 77' truss without special permits. They can build and deliver longer ones but it costs more....    Did not ask what the maximum is but it is also dependent on access to the job site.

 

Definitely a good question for your local truss supplier though. ;)

54’ was always Max in Washington state. 46 in upper Wisconsin due to terrain.

That is your error you need to make the chord spans maybe 4 feet so that the webbing centres are correct, play around with the settings indicated in chopsaws post above.

Kiwideziner,  Thank you very much  I used 12' for the bottom chord and 6' for the top chord.  The results was what I was looking for.  This Forum has bailed me out many times and I thank all of you who answered my plea for help.   Junior
