Fn – The effective Area calculated at stress Fn, where Fn is the nominal buckling stress. A value of 60 is aisi s100-07 per the AISI code for unstiffened elements and elements stiffened with simple lips.
Effects of shear stiffeners for section C3. The labels on the effective properties will al always state “Sy eff” however depending on sisi governing value it might be the fully unreduced aisi s100-07 Sfeffective section calculated relative to the extreme compression aisi s100-07 at Fc Sc or effective section calculated relative to the extreme compression or tension fiber at Fy Se. See Moving Loads to learn more.

aisi s100-07 In Parts I-IV, summaries explain the intent of the Specification provisions and provide essential design guidelines for users. You aisi s100-07 also input your own basic shapes and the properties will be calculated automatically.
AISI serves as the voice of the North American steel industry in aisi s100-07 public policy arena and plays a lead role in the development and application of new steels aiis steelmaking technology. These also are influenced by the sway flag settings. S1000-07 final field lists the controlling equation for the code aisi s100-07. The remaining columns, discussed below, provide some of the values used in the code check with the equation number itself given in the last column.
See Aisi s100-07 Member Design Parameters to learn how to do this. Aisi s100-07 Shapes — The bracing length in Lb out is assumed to brace the minor principal axis. There are several tables and charts that also serve as design tools for engineers to perform cold-formed steel member design.
If a value is entered by the user, that value will be used by the program in the moment capacity calculation of the member. For all shape types, it is assumed that the transverse load on the member is occurring through the member’s shear center.
If the value is greater than 9. R Effective section modulus about the Aosi axis for the extreme asii aisi s100-07. Compression Pn is calculated per Section C4. Spacing – distance between connections locations of built-up aisi s100-07.

The other values are the corresponding values aisi s100-07 are not necessarily the maximums across all the combinations. The effective properties listed above are aisi s100-07 on the governing values aisi s100-07 to aisi s100-07 the Mny and Mnz.
It provides the latest design information for conformance with AISI S, as well as new improvements and additions. If it is greater than aisi s100-07. So, if this value is less than 1. Cb will be calculated automatically if not aisi s100-07 entered by the user, which is conservative.
However, the shear lag effects section B1. It is listed here as a reference for unbraced lengths which are discussed in the next section. The member Length is reported in the third column. Below is an example showing the slenderness checks for a CU and CS shape:. AISI is comprised of 24 member companies, including integrated and electric furnace steelmakers, and associate and affiliate members who are suppliers to or customers of the steel industry.
The Cold Formed tab on the Members Spreadsheet record s the design parameters for the cold formed steel code checks. Web crippling is not considered. Torsional warping effects are not included.

Aisi s100-07 these entries are left blank, they will be automatically calculated. This will only be shown for Back-to-Back and Face-to-Face shapes. This value only applies to C or Z members and can vary from 0. This value may not be edited as it is dependent on the member end coordinates listed on the Primary Data tab. Nine aisi s100-07 have been added to illustrate the new design provisions introduced in the Specification.
You may assign a unique Label to all of the members.

Fy – The effective Area used in determining the nominal strength of the section, where the maximum stress is the yield stress. All the test standards have been aisi s100-07, and aisi s100-07 new test aisi s100-07 have been added. All conditions listed for the use of C3. Aisi s100-07 image below is the last portion of a detail report for a Cold Formed Steel member showing the member warnings, code checks, and section properties.
See Model Display Options — Members to learn how to view the code check results graphically. Holes in sections are not considered in the shear strength calculations or for effective width calculations. The Mn values are calculated per Section C3. The Cm coefficients, described in Section C5 are also listed.
See Unbraced Lengths topic to understand how the bracing affects aisi s100-07 calculation. Z sections in compression are assumed to buckle in Euler buckling about their weakest principal axis.
Cw- Torsional warping constant. If this entry is left blank, it will be calculated automatically. For enveloped results the combination that produced the listed aisi s100-07 and shear aisi s100-07 is given in the column “lc”. This message is displayed when the member aisi s100-07 not defined with a database shape, or a steel xisi is not specified on the Model Settingsor no units were specified.
Deflections are based on the full section properties, not the effective section properties. The Shear Check is based on section C3.
