Just 2x4 framed walls correct?


Yeah, but I am worried about the strength of tapcons if a hurricane were to come through.

The anchors will hold if drilled and epoxied in place.

Follow the load path from roof down and install Simpson strong tie clips where needed

the latest high wind construction guides for slab on grade construction require straps embedded in the concrete and nailed to the bottom plate or the wall studs, or 5/8-inch diameter anchors bolts spaced at 18 inches or less. They also require 3-inch by 3-inch by 1/8-inch thick washers between the nuts and the bottom plate if anchor bolts are used. If you have a wood frame floor, anchor bolts don't work.


quote:

Wall bottom plates shall be anchored to a slab-on-grade foundation system with anchor bolts having a minimum bolt diameter of 5/8 inch and 3"x3"x1/8" washers. A minimum of one anchor bolt shall be provided within 6 to 12 inches of each end of each plate. Anchor bolts shall have a minimum embedment of 7 inches in concrete slabs-on-grade. Anchor bolts shall be located within 12 inches of corners and at spacings as specified in Table 303.3.2 for anchor bolts resisting lateral, shear, and uplift loads. Approved alternative plate anchors and wall anchoring systems shall be installed in accordance with the manufacturer’s published recommendations and shall meet the following design requirements.
