* indicates ultimate load divided by 3 for the design capacity. 4’ span is a minimum two span condition.

Panels require a minimum of 1-1/2” bearing. I-Joist splines are spaced 4’ o.c.

Floor panels should have a 3/4” minimum top skin or a 7/16” top skin overlayed with 7/16” finish flooring perpendicular to the panels.
