Uplift loads account for a maximum 2-foot aiei overhang. In accordance with Table 3. Read Full Article Hide Comments. As an alternative to the blocking panel shown in Figure 3a blocking panel designed to resist the lateral wind loads for the roof diaphragm in accordance with the AWC WFCM shall be permitted. Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls.

2211.7 Prescriptive Framing

Footings for stemwall foundations shall be reinforced with two No. The uplift connection capacities at this inset porch shall be not less than required by Table Required foundation weight need not be evaluated for the rectangle and wind direction noted, if there are no vertical offsets and roof framing between rectangles. Monolithic interior slab-on-grade footing.

Ring-shank nails shall have a minimum bending yield strength of ksi In order to choose the appropriate connector, please check with the connector manufacturer.

Building length shall be equal to or greater than that shown in the tables. Light-framed construction shall be in accordance with Section Floor Systems Design Manual: Stem wall with slab on grade. Required interior stemwall foundations shall be the same as for exterior walls. For a rectangular building plan, required foundation weight per foot shall be evaluated for each horizontal direction; the largest required foundation weight per foot shall be used.


All footing dowel bars shall have a standard degree 1.

Stem wall with light-framed 1 st floor b. An 8-inch by 8-inch mm by mm concrete or CMU bond beam with one No. Minimum bar lap shall be 25 inches mm. This standard contains figures showing connectors. The provided foundation weight per foot plf shall be determined by one of the following methods:.

Connectors and fasteners shall meet the requirements of Section in addition to the requirements of the standards referenced in Section Stemwalls shall extend no more than 3 feet mm above the finish grade and shall be constructed in accordance with Section This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies.

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 uplift connection type and location shall be as indicated in Figures 2 through 4. 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.

The outer bar of foundation reinforcing shall be continuous around corners using corner bars or by bending the bar. Screws, bolts and nails shall be corrosion resistant by coating, galvanization or composition stainless steel, nonferrous metal or other suitable corrosion-resistant material.

But, why would AISI develop six discrete framing standards as opposed to one design manual?

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 aixi soil mobilized by the uplift of the foundation.

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. This chapter prescribes construction requirements for buildings in which all exterior walls above the foundation are of light-framed construction using wood or cold-formed steel framing members and where the building meets the parameters and requirements of Chapter 1. Tabulated required connection capacities are allowable stress design loads.

In addition, the continuous foundation shall be sized so that the foundation weight per foot plf is not less than the aizi required foundation weight per foot plf specified in Table 2. Standard iasi washers shall be permitted for cold-formed steel framing with standard hole sizes. The size of continuous foundations shall be as required to meet the minimum requirements of aisii International Residential Code and the minimum size specified in Table 1.
