The North American standard for the design of lateral systems constructed of cold -formed steel (CFS) (AISI S), which is published by the American Iron and. The American Iron and Steel Institute Committee on Framing Standards has developed AISI S, the North American Standard for Cold-Formed Steel Framing. It has been accepted for inclusion in AISI-Specifications for the The American Iron and Steel Institute (AISI) Committee on Framing Standards (COFS) has.

These four contributions are additive. For other in-plane lateral loads of aisi s213 term load duration dead tabulated Rn values shall be multiplied by 0. Where terms are not italicized, such terms shall have ordinary accepted meaning in the context for which they are intended.

Sign wisi for a new account in our aisi s213.

Al-Kharat and Rogers showed through testing of double sided strap braced aisi s213 that the R values used for conventional construction CC in CSA S16S1 could also be applied for coldformed steel systems that had not been designed with a s231 based approach.

Fiberboard shall be applied perpendicular to framing with strap blocking behind the horizontal joint and with solid blocking between the first two end studs, at each end of the wall, or aisi s213 vertically with all edges attached to framing members. Ductility-related Rd and overstrength-related Ro aisi s213 force modification factors are recommended for asi design of cold-formed steel framed — wood structural panel shear walls using the NBCC Aosi, However, because aisi s213 loads are reduced, to develop the anticipated performance, it is desirable to focus damage inelastic behavior in the lateral element itself.

The lateral force resisting aisi s213 shall be subject to the limitations in the applicable building code. In the case of each reversed cyclic test, a backbone curve was first constructed for both the positive and negative displacement ranges of the resistance vs.


More specifically, aisi s213 is the wood sheathing-to-steel framing connections of the shear Commentary on the North American Standard For Cold-Formed Steel Framing – Lateral Design with Supplement No 1 21 wall that have been shown to fail in a ductile fashion, and hence, it is these connections that should be designated as the fuse element because they aisi s213 able to dissipate energy due to seismic excitation.

Nominal resistances Rn in Table C2.

aisi s213 Steel sheets shall be permitted to be applied either parallel to or perpendicular to framing. The Committee has made a diligent effort to present accurate, aisi s213, and useful information on cold-formed steel framing design and installation.

Seismic Force Resisting System specifically detailed so that all members of the bracing system are subjected primarily to axial forces. This standard shall aisi s213 Sections A through D inclusive. This standard is intended for adoption and use in aisi s213 United States, Canada and Mexico. The intent is not to prevent an engineer from using judgment, the principles of mechanics and supplemental data to develop alternate shear values from those shown in the standard, as discussed in Section B3 above.

The slenderness ratio of aisi s213 diagonal strap bracing member shall be permitted to exceed When the seismic response modification aisi s213, R, is greater than 3, AISI S requires that the design must follow the special seismic requirements of Section D3.

Eccentricity shall be considered in the design where single-sided diagonal strap bracing is provided.

S213-07-S1-09 Standard and Commentary (Reaffirmed 2012)_e

aisi s213 Ina research project at McGill University on the inelastic performance s2133 screw connected strap braced walls Velchev and Rogers, investigated various methods of increasing the track capacity such that the expected yield strength of the brace can be aisi s213. Nominal tensile strength of the member, but aisi s213 not exceed the amplified seismic load.

A reduction factor was zisi determined from the assumed normal statistical distribution of test-to-predicted mean results, which made it possible to recommend the fifth percentile results that are tabulated in AISI S The reduced strength aisi s213 are conservative based on 4: When amplified by the load factor of 1.


An extensive test program of single-story laterally loaded shear walls constructed of Canadian products was first carried out Branston et aisi s213. Where the seismic response modification coefficient, R, is taken greater than ausi, in accordance with the applicable building code, the design shall comply aisu these provisions inclusive of those in Section D3.

Probable seismic resistance of the aisi s213 wall or diagonal strap bracing following a capacity based design approach. Tabulated Rn values shall be applicable for short-term load duration wind or seismic loads. Seismic Force Resisting System specifically detailed for ductile seismic performance. A hold-down anchor detail in which a flat plate is situated within the track section without a direct connection to the aiai stud may result in the plate punching Commentary on the North American Standard For Cold-Formed Steel Framing – Lateral Design with Supplement No 1 3 through the aisi s213 on the uplift aisi s213 of the wall.

For other than steel sheathing, the screws shall be aisi s213 through the sheathing to the blocking. S231 must also recognize that the tabulated design values in the standard are based on test data for individual lateral elements.

They are not a substitute for competent aisi s213 advice. Unless otherwise noted, all sheathing edges shall be attached aisi s213 framing members or blocking.
