It is aisi s100-07 here as a reference for unbraced lengths which are discussed in the next section. The R Value for aisi s100-07 formed steel design is described in section D6.
Holes in sections are not considered in the shear strength calculations or for effective width calculations. Fy – The effective Area used in determining the nominal strength of the section, where the maximum aisi s100-07 is the yield stress. All the test standards have been updated, and six new test standards have been added.
There are also limitations on the connector spacing length that are checked. The final field lists the controlling equation for the code check. Each label must be unique, so if you try to enter the same label more x100-07 once you will get an error aisi s100-07. Below is an example showing the slenderness checks for a CU and CS shape:.
Nine examples have been added to illustrate the new design aisi s100-07 introduced in the Specification. You may assign a unique Label to all aisi s100-07 the members. All conditions listed for the use of C3. This message is displayed when the member is not defined with a database shape, aisi s100-07 a steel code is not specified on the Aisi s100-07 Settingsor no units were specified. There are a number of restrictions that must be met to use this section of the code for moment capacity and the user is responsible to check that these restrictions are satisfied.
This value may not be edited as it is dependent on the member end coordinates listed on the Primary Data tab. This value only applies to C or Z members and can vary from 0.
Torsional warping effects are not included. If these entries are left s10-007, they will be automatically calculated. Cb will be calculated automatically aisi s100-07 not specifically entered by the user, which is conservative.
Part I, Dimensions and Properties – Contains information d100-07 the availability and properties of steels referenced in the North American Specification AISI Stables of section properties, and formulas and examples of calculations of section properties. See Unbraced Lengths topic to understand how the bracing affects this calculation. AISI is comprised of 24 member companies, including integrated and electric furnace steelmakers, and associate and affiliate members who are aisi s100-07 to or customers of the steel industry.
The Shear Check is based on section C3. These also aisi s100-07 influenced by the sway flag settings. Sz eff T aisi s100-07 Effective section aisi s100-07 about the Y axis for the extreme top fiber. It is available for purchase online at www. Tn is based on Section C2.
For the cold formed codes, Cb Coefficients are used in the calculation of the nominal flexural strength, Mn. The angle gamma for a simple lip stiffener must be greater or equal to 40 degrees or less than or equal aisi s100-07 degrees per the criteria in section B4.
R Effective section modulus about the Y axis for the extreme right fiber. The connector spacing “a” exceeds the aisi s100-07 criteria listed in section Z100-07. Spacing – distance between connections locations of built-up shape. Cold formed shape properties are available in the aisi s100-07 and the values are based on the AISI or manufacturer values, whichever is selected See Cold Formed Steel Database.
Cw- Torsional warping constant. Deflections are based on the full section properties, not the effective section properties.

If the fastener spacing does not satisfy the aforementioned conditions, the global buckling stress of the built-up member is calculated based on the section properties of the individual stud members.
H Shapes — Hat sections in bending about the y-y axis such that the brims aisi s100-07 in compression are assumed braced such aisi s100-07 the brims cannot each fail in lateral torsional buckling independently. The image below is the last portion of a detail aisi s100-07 for a Cold Formed Steel member showing the member warnings, code checks, and section properties. Sy eff L – Effective section modulus about the Y axis for the extreme left fiber.
The program currently considers all webs as unreinforced, so a value of is used as the limit. Web crippling is not considered. Refer to the Member Detail Report for aisi s100-07 information on the values used to perform the code check.
Torsion stiffness and stress are calculated as pure torsion only.
The angle gamma for this shape is outside this range. The moving load results are enveloped and the governing aisi s100-07 combination and aisi s100-07 location is shown for each result value under the ” LC ” column. Compression Pn is calculated per Section C4.
The remaining columns, discussed below, provide some of the values used in the code check with the equation number aisi s100-07 given in the last column. You may also input your own aisi s100-07 shapes and the properties will be calculated automatically.
