IRC Table R602.3(5) vs. Table R602.3.1 on the max height and spacing of 2×4 bearing stud walls
I’m designing a monopitch (shed-roof) residential addition in CZ6. I’m looking into using 2×4 walls with exterior EPS. Design calls for a 10′ high wall on the tall side of the shed and just under 8′ on the short side. I’d like to maintain all stud spacing at 24″ OC. Table R602.3(5) seems to indicate I can do this, specifically calling out 2×4 studs at 24oc up to 10′ high between lateral supports. However, what about Table R602.3.1, “Maximum allowable length of wood wall studs exposed to wind speeds of 115mph or less?” This seems to limit 10′ 2x4s to 16oc or less spacing even for small buildings. The two tables seem in conflict, so I suspect I’m mis-applying them. Any insights? I’m in Exposure B, wind speed 115mph. Building width is 16 feet clearspan. Thanks!
