Uplift loads; and 4. Stemwall foundations with a slab-on-grade shall meet the wall-to-foundation anchorage requirements specified in Section The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.
Roof and floor framing shall span in the same direction. Piles supporting structures shall be designed by a registered engineer or architect.
Open structures or portions of structures shall be in accordance with S203 The connectors are shown for illustrative purposes only. Corrosion resistance exhibiting not more than 5-percent red rust after hours exposure for nails, hours for roof tile fasteners or hours exposure for other carbon steel fasteners in accordance with ASTM G85Annex 5.
Where figures show masonry units for walls, concrete walls shall be permitted. Other reinforcement shall be provided as required in Chapter 4 of the International Residential Code. This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies.
2211.7 Prescriptive Framing
Stemwalls illustrated in Figures 23 and 4 shall be constructed with minimum 8-inch-nominal mm concrete or concrete masonry and shall comply with the following:. In order to choose the appropriate connector, please check with the connector manufacturer.
Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. Use shall be limited to design wind speeds not greater than miles per hour Lateral load perpendicular to the plane of the wall.
Shear in the plane of the wall; 2. Stemwalls shall extend no more than 3 feet mm above the finish grade and shall be constructed in accordance with Section Where anchor bolts are used for required anchorage of wood frame construction, anchor bolts shall have a minimum 3-inch by 3-inch by 0.
Footings for stemwall foundations shall be reinforced with two No. Concrete slabs and footings shall be poured as a monolithic unit. Permitted only where ultimate design wind speeds do not exceed mph and the structure does not exceed two stories in height. Connectors and fasteners shall meet the requirements of Section in addition to the requirements of the standards referenced in Section Where anchor bolts are used to transfer uplift from wood frame construction to the foundation, anchor bolts shall have a minimum 3-inch by 3-inch by 0.

C NP NP NP NP. An approved itemized calculation of the foundation weight per linear foot including the weight of the foundation, tributary slab-on-grade, plus the weight of any soil mobilized by the uplift of the foundation.
Strap spacing shall not exceed 3 feet mm on center, except that two straps may be provided at pier spacing not exceeding 6 feet mm on center. Girders, including connections to piles, shall be designed by a registered engineer or architect. Inset porches, in accordance with Figure 1shall be permitted in accordance with the details in Figures 2 through 4. Connectors resisting uplift of the roof framing shall be fastened to the top plate on the same side of the wall as the top-plate-to-wall uplift connection.
The provided foundation weight per foot plf shall be determined by one of the following methods:. Screws, bolts and nails shall be corrosion resistant by coating, galvanization or composition stainless steel, nonferrous metal or other suitable corrosion-resistant material. The uplift connection type and location shall be as indicated in Figures 2 through 4. In addition, the continuous foundation shall be sized so that the foundation weight per foot plf is not less than the minimum required foundation weight per foot plf specified in Table 2.
