Tag: AISI S Code Update: Revisions Finalized for the IRC. This blog post continues our series on the final results of the ICC. AISI S/S DISCLAIMER The material contained herein has been developed by the American Iron and Steel Institute (AISI) Committee on Framing . the AISI Prescriptive Method (AISI S w/S). The loads, load combinations, and other design parameters used to develop the provisions in the AISI.
AISI Publishes Standard for Cold-Formed Steel Framing
Stemwall foundations with a slab-on-grade shall meet the wall-to-foundation anchorage requirements specified in Section Fasteners and connectors that are exposed directly to the weather in areas within 3, feet m of a saltwater coastline or subject to salt corrosion as determined by the building official, or in contact with treated wood, shall comply with Sections Stem wall with slab on grade. Shear in the plane of the wall; 2. Open structures or portions of structures shall be in accordance with Section 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.
In order to choose the appropriate connector, please check with the connector manufacturer. Wood structural panel wall sheathing or siding shall be permitted aiisi be in accordance with Section Masonry materials and construction shall be in accordance with Section 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:.
See Figures 5a5b and 5c for additional detailing requirements. Not less than 0. Roof sheathing attachment in wood light-framed construction shall be in accordance with Section Tabulated required connection capacities are allowable stress design loads. Monolithic interior slab-on-grade footing.

Uplift loads; and 4. Floor Systems Design Manual: Under slabs, required continuous interior footings shall be aiso width, Wand thickness, Trequired by Section Dowels shall lap wall reinforcing a minimum of 25 inches mm. The following need not be evaluated to determine minimum foundation weight per foot in accordance with Figure 1.
Screws, bolts and nails shall be corrosion resistant by coating, galvanization or composition stainless steel, nonferrous metal or other suitable corrosion-resistant material. Stemwalls illustrated in Figures 5a5b and 5c shall be constructed with a minimum 6-inch mm hollow clay brick or minimum 3-inch 76 mm solid clay brick and minimum 4-inch mm hollow concrete masonry unit in accordance with Figure 5a5b or 5c and shall comply with the following:.
Except as otherwise noted herein, interior walls and partitions may be of either wood or cold-formed steel framing. Close Explore the durability and resiliency of cold-formed steel framing when confronted with fire, cold weather, hurricanes, and flooding.
Light-framed construction shall be in accordance with Section Stemwalls shall extend no more than 3 feet mm above the finish grade and shall be constructed in accordance with Section Footings for stemwall foundations shall be reinforced with two No. Vertical reinforcement shall terminate in the bond beam with a standard hook. Concrete slabs and footings shall be poured as a monolithic unit.
Where the nominal dimension of 8 inches inch mm is used for masonry units, the equivalent dimensions for concrete walls shall be permitted to be 7. The illustration of the connectors is not intended to endorse any connector manufacturer.
Permitted only where ultimate design wind speeds do not exceed mph and the structure does not exceed two stories in height. Girders, including connections to piles, shall be designed by a registered engineer or architect. Corrosion resistance exhibiting not more than 5-percent red rust after hours exposure in accordance with ASTM B Where anchor bolts are used for required anchorage of wood frame construction, anchor bolts aizi have a minimum 3-inch by 3-inch by 0.
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. Fasteners and connectors shall be in accordance with Section From tothe AISI Committee on Framing Standards developed nine aaisi framing standards to cover specific aspects of cold-formed steel framing. The simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document.
This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies.
An 8-inch by 8-inch mm by mm concrete or CMU bond beam with one No. Shear wall overturning hold-down loads. 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.
This has been an often asked question by framing design engineers. Read Full Article Hide Comments. The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.
In addition, the continuous foundation shall be sized so that the foundation ais per foot plf is not less than the minimum required foundation weight per foot plf specified in Table 2.
Connectors and fasteners shall meet the requirements of Section in addition to the requirements of the standards referenced in Section
