CFS 12

CFS^® is a comprehensive general-purpose cold-formed steel componentdesign tool that performs calculations according to the AISI 2016 Editionof the North American Specification for the Design of Cold-Formed SteelStructural Members (S100-16), and the 2002 Edition of the ASCE Specification for theDesign of Cold-Formed Stainless Steel Structural Members (ASCE-8-02).

System Requirements

• Windows Vista, 7, 8, 8.1, 10 (32-bit or 64-bit)
• Microsoft.NET Framework 4.5

Specifications Supported

• AISI S100-16/S1-18 - ASD, LRFD, LSD
• AISI S100-16 - ASD, LRFD, LSD
• AISI S100-12 - ASD, LRFD, LSD
• AISI S100-07/S2-10 - ASD, LRFD, LSD
• AISI S100-07 - ASD, LRFD, LSD

• AISI 2001 - ASD, LRFD, LSD
• AISI 1999 - ASD and LRFD
• ASCE 8-02 - ASD and LRFD (stainless steel)

Section Versatility

The Section Wizard makes it quick and easy to create the geometryfor common shapes and the graphical interface allows you to createvirtually any cold-formed steel shape, including closed shapes,built-up sections, stiffeners, and elements with holes. You may choose froma long list of predefined carbon and stainless steel materials,or customize the material properties as needed. Additionally,several libraries are provided for commonly available componentshapes in the industry. Section geometry can imported and exportedusing DXF.

Quick Design

The CFS Quick Design tool makes design checks for industry standardshapes very fast and easy. It will even optimize the section thickness,flange size, and yield stress to meet your design requirements. And ifyou need to investigate the design in more detail, simply create thefull analysis problem with a single click.

Analysis Wizard

The Analysis Wizard assists in the creation of a variety of designproblems such as beam-columns, continuous beams, and multi-span beams withlaps. Analysis problems consist of members, supports, braces, loadingsand load combinations. Transverse loads may be concentrated ordistributed, and applied at any angle, thus producing biaxialbending. Axial loads may include eccentricities which induce additionalmoments. You can display and print diagrams for reactions, shears,moments, and deflection, including envelope diagrams for all loadcombinations.

Computations

• Full, net, and effective section properties using exact integrations
• Strengths for compression, tension, moments, shears, bimoment, and web-crippling
• Strength increase from cold work of forming
• Member checks for combined axial/bending, bending/shear, bending/torsion, and bending/web-crippling
• Calculation trace available for additional details
• Messages given for exceeded limits such as w/t, D/t, KL/r, etc.
• Elastic buckling anaylsis using finite strip method
• Complete documentation included as an integrated help file

Elastic Buckling Analysis

A powerful feature of CFS is the elastic bucklinganalysis of any cross-section using the finite strip method. Someshapes may be subject to a mode of buckling where the section distorts.This tool helps the engineer to utilize the Direct Strength Method(DSM) according to the AISI Specification.

Light vs. Full License

CFS is free to download and install. Without the purchase of a full license, the application will runin 'light' mode with a reduced set of features and limitations on section complexity.This mode is ideal for educational use and will give you a feel for what the fullCFS software has to offer. You may then choose to purchase a license forthe full version CFS. Here is a comparison between the full and light modes.

CFS12 Automation Module

For users of CFS 12, this optional software component providesthe full computational engine of the CFS application for customizedautomation of cold-formed steel calculations in your own applications.There are numerous ways to use this library, including spreadsheetmacros, creation of spreadsheet tables, automated design checks usingexternal analysis data, and even full-fledged structure design automation.

System Requirements

• Windows Vista, 7, 8, 8.1, 10 (32-bit or 64-bit)
• Microsoft.NET Framework 4.5
• Development environment supporting COM or .NET 4.5
• CFS 12 software installed and licensed (network or single-user, with automation)

Additional Info

The calculation methods in CFS12 can use existing section files orsection libraries created using CFS, or you can define new sections 'on the fly'to analyze. These methods perform operations such as retrievalof section information, computation of gross section properties,net section properties, effective section properties, fully bracedstrengths, and design checks for axial, bending, shear, web-crippling,combined axial/bending, combined shear/bending, and combined web-crippling/bending.

The CFS12 module includes complete documentation of the objects,methods, and properties, and some sample code to get you started. Thisdocumentation is available from our Download page.

This product is incorporated into the structuralanalysis application VisualAnalysis for performing cold-formed steeldesign checks on 3D structures. The VisualAnalysis software isoffered by IntegratedEngineering Software.

Release NotesRequirements

Simpson Strong-Tie® CFS Designer™ gives cold-formed steel (CFS) Designers the ability to design CFS beam-column members according to AISI specifications and to analyze complex beam loading and span conditions. Intuitive design tools automate common CFS systems such as wall openings, up to eight stories of interior or exterior load-bearing studs, compression posts for shearwalls, eight stories of stack x-brace or shear wall design,floor joists with unbalanced live-load combinations, and low-wall moment connections. CFS Designer™ allows the design of multiple systems within the same job file, and supports connection design for specific Simpson Strong-Tie® curtain wall and bridging connectors like the SUBH u-channel bridging connector.

Additional features include:

• Simpson Strong-Tie CFS Designer provides a wall stud and beam stud design tool that allows Designers to model up to 3-span beams with overhangs at each end. Designers can also add a complex array of distributed, sloped, and point loads.
• CFS Designer automates the complicated design provisions of the AISI CFS Specification. Stress checks include; braced and unbraced moment, shear, web-crippling, axial strength, and all code-required combined interactions. The 2016 w/ S1-18, 2016, 2012, 2010, 2007, and 2004 AISI Specifications are covered by the software.
• CFS Designer enables the design of single stud and track members, built-up box-sections, back-back sections, nested stud, track sections, and proxheaders. In addition, when CFS members are not a practical solution, the software enables the design of HSS sections according to the AISC 13th Ed.
• In addition to modeling beam problems, CFS Designer also provides a set of tools that automate the design of wall openings for windows and doors, eight stories of x-braced and sheathed shearwalls, floor joists, roof rafters, up to eight stories of load-bearing studs and provides the design of low-wall moment connections.
• CFS Designer can simplify your curtain wall connector, anchorage and bridging design. This software automates the design of by-pass connectors, slotted track, slip track, base track as well as SUBH and MSUBH bridging connectors.
• CFS Designer provides an intuitive user interface that enables the engineer to save engineering models in a single file. Output files are generated in Adobe Acrobat format and can be saved as separate files as needed.
