Spanning 20ft
« on: September 15, 2019, 11:54:41 PM »
I知 needing to span 20ft but can only mill 16ft. I知 thinking of using a whole log it痴 beetle killed spruce.
I have plenty of them standing dead for several years now.
If I知 to use one. How big should it be for snow load? I知 in south-central Alaska.

Hey emery,sure. There is a log beam calc in the red toolbox, bottom of the column on the left of this page under Don P's calcs> beam and column calcs.

You didn't give enough info to answer the question but look over the calc, you might not need more than that.
