I'm building a loft ladder with alternating-tread steps. The stringers are 2x6 White Spruce, and I'm hoping to build the steps out of the same material.
The span for the steps is 21". Code requires handling a maximum point load of 300 pounds at the step center, or a live load of 40psf, whichever is higher.
If I've done the math right, steps made from 2x6 white spruce laid flat will meet that requirement.
However, I'm unable to find reliable information about the connection between the steps and the stringer. I'm hoping to attach the steps with three 16d 3.5" nails on the wide side, and two 16d 3.5" nails on the narrow side.
My main concern being the limited amount of wood above the fastener in the step member causing failure.
How can I determine the maximum load the connection can bear in this configuration:

I suggest cutting slots in the stringers to hold the steps putting the load on wood and not 3 nails which will work loose or split the wood.
