Frequently Asked Questions

We’ve compiled a short list of frequently asked questions we receive from structural engineers using our SteelSmart System light steel framing design software and SteelSmart Framer BIM framing software to design and detail cold formed steel studs, track, joists and connectors.

Installation Questions

Do I need to uninstall a previous version of SSS from my computer?

No, Steel Smart System 7 will automatically remove previous versions of SSS before installing.

How do I activate my copy of SteelSmart System?

After the initial installation to your computer hard drive, click on the SSS desktop icon. When the SteelSmart System window appears, it will prompt you for your ASI Portal username and password, enter them, then press activate and your license will automatically activate.

Is there a SSS network license option available?

Yes, a network license option is available.  Network administrators can purchase licenses as normal through the website, but a separate link will be provided for download.  Please contact support@steelsmartsystem.com for more information or access to the download.

Technical Design Module Questions

What design codes does SSS use?

The following design codes are available within SSS:

  • 2015 IBC with AISI S100-12 and ASCE 7-10
  • 2012 IBC with AISI S100-07/S2-10, and ASCE 7-10
  • 2009 IBC with AISI S100-07 and ASCE 7-05
  • 2006 IBC with AISI-NAS 2001/04 Supplement and ASCE 7-05
  • Canadian NBC 2010 with AISI S100-07/S2-10

When I click on some of the design modules I get a message that says “This component is not active in the current version of SSS.” How can I get a version of SSS with this component?

Modules are available depending on which type of license was purchase. Please contact support@appliedscienceint.com for license options and pricing.

How can I enter the type of sheathing used for designing a wall?

SSS does not directly allow the user to input the type of sheathing used when designing wall components. When using the 2009 IBC, 2012 IBC, 2015 IBC, or the Canadian NBC 2010 as the design code, SSS allows the input of kφ, the distortional buckling rotational stiffness. When designing according to the 2006 IBC this value is not used and sheathing effects are not taken into consideration for design of wall components. More information regarding this value and sheathing effects can be found in the SSS 7 Technical Manual.

How can I enter axial loads on curtain walls?

In some cases axial loads other than self-weight and dead load must be added to a curtain wall. To enter axial loads on a curtain wall, select the User-Defined layout and enter the axial loads using the member loads table. Select the desired load case and click the (+) sign to enter the load value and its location. To place a load at the top of a member, the X/L ratio should be entered as one.

When I execute a design I get a message stating “Either the bridging member or the bridging clip was not available.”

If you are unsure of what method of lateral bracing to specify or of a reasonable bridging spacing, select Auto Calculate from the Bridging Member drop-down menu.

How are wind loads which are applied to window and door openings distributed to jamb, header, and sill members?

Users are given the option to select from four different wind distribution methods. Four-way distribution, two-way distribution on header and sill members, two-way distribution on jamb members, and unglazed conditions can be analyzed. More information about these selections can be found in the SSS 7 Technical Manual.

CFSUM Questions

What does CUFSM stand for?

Cornell University Finite Strip Method.

What is CUFSM?

CUFSM is a tool that calculates elastic buckling loads for use with the Direct Strength Method of the AISI S100-07/S2-10 Standard and later versions of the standard.

Where can I get more information about CUFSM?

More information about the CUFSM tool embedded in SSS can be found here: http://www.ce.jhu.edu/bschafer/cufsm/.
