Customer Question
Im curious if a...

Im curious if a 6" x 6" in western red cedar can span 18'. dead load bearing only it's own weight. were hoping to use them with 6"x6" posts serving as perimeter racking. thanks

Tutor's Assistant: OK. Tell me a bit more about what's going on so we can help you best.

Its a pergola with (4) 6X6 corners and connected by a perimeter beams that need to span approx 18' between posts side to side and about 16' front to back

Tutor's Assistant: Is there anything else important you think the Structural Engineer should know?

I dont think so- just need to know if this will work and not sag under it's own weight over time

the posts and cross supports are the 6x6's for uniformity. were planning to fabricate steel 90 degree cuffs on the corners for rigidity but as you can see it's mostly for rack stability. just want to know since its really not holding any weight aside it's own if it will hold up and not sag over time. thank you
