... here I am using this example of our 24 x 72 cabin, subject to rather huge snow loads ... to illustrate header design. Let's design a header for one of the side walls where we have an 8'-0" window opening. The header will have to carry snow (and dead) load from above. Rafters span from the ridge beam over the wall and overhang 2'.
Let's do it.
On this post we will use the `Cornell Beam Calculator'.
