Summary
These calculations are for a 14'x24'=336sf one-story addition to an existing one-story house. The new
construction will be conventional wood construction consisting of a concrete footings, post & beam floor,
2x6 exterior walls, and stick framed roof or engineered roof trusses.

Lateral Design: Seismic vs Wind
The lateral loads will be transferred to the exterior walls by the roof diaphragm. The calculations will show
that wind governs design and the largest shear per linear foot on any of the new walls is 133 plf.This value
is very small and will be resisted by 7/16 OSB sheathing with 8d at 6/12 nailing which is good for 280plf per
Table 2306.3.
