In Parts I-IV, summaries explain the intent of the Specification provisions and provide essential design guidelines for users. Part IV, Connections – Contains tables to aid in connection design and example problems. Refer to the Member Detail Report for more information on the values used to perform the code check. However, the shear lag effects section B1.
There are several tables and charts that also serve as s tools for engineers to perform cold-formed steel member design. Nine examples have been added to illustrate the new design provisions introduced in the Specification.

A value of 60 is used per the AISI code for aisi s elements and elements stiffened with simple lips. In Parts I-IV, summaries explain the intent of the Specification provisions and provide essential design guidelines for users.
Kt in section Aidi. There are several tables and charts that also serve as design tools for engineers to perform cold-formed steel member design. Part I, Dimensions and Properties – Contains information on the availability and properties of steels referenced in the North American Specification AISI Stables of section properties, and formulas and examples ss100-07 calculations of section properties.
Nine examples have aisk added s1000-07 illustrate the new design provisions introduced in the Specification. The Mn values are calculated aisi s Section C3. This will be one of the equations from Section C5 or Section C3.
H Shapes s100-07 Hat aisi s in bending about the y-y axis such that the brims are in compression are assumed braced such that the brims cannot each fail aisi s lateral torsional buckling independently. Below is an example showing the slenderness checks for a CU and CS shape:.

Part IV, Connections — Contains tables to aid in connection design and example problems. Effects of shear stiffeners aixi section C3. Compression Pn is calculated per Section C4. The R Value for cold formed steel design is described in section D6. The member Length is reported in the third column. All the test standards have been updated, and six new test standards have been added. Cw- Torsional warping constant.
AISI Publishes Cold-Formed Steel Design Manual
It provides the latest design information for conformance with AISI S, as well as new improvements and additions. Aisi s — The effective Area used in determining the nominal strength of the section, where the maximum stress is the yield stress.
It is available for purchase online at www. Part V, Supplementary Information – Contains a table of Specification cross-references to examples provided in the Design Manual, design procedures not included in the Specification, and additional information to assist users of cold-formed steel.
There are also limitations on the connector spacing length s—07 are checked. Sy eff L — Effective section modulus about the Y axis for the extreme left fiber. See Moving Loads to learn more.
All conditions listed for the use of C3. The effective properties listed above are based on the governing values used to determine the Mny and Mnz. These also are influenced by the sway flag settings.
If aiai entries are left blank, they will be automatically calculated. All the test standards have been updated, and six new test standards have been added. The final field lists the controlling equation for the code check.
Cold formed shape properties are available in the database and the values are based on aisi s AISI s manufacturer values, whichever is selected See Cold Formed Steel Database. The aisi s Shape or Section Set is reported in the second column. See the Unbraced lengths for Cold Formed Steel section for the full details.
