CS4 POSTPROCESSOR

         
Are You a civil engineer occupied with design of lightweight steel structures? Are You interested in a technology that allows to build cost-effective steel structures? Are You developer in a software house that deploys advanced structural analysis software used for steel buildings? 
Are You interested in being always up to date in design of cold-formed or thin-walled members?
Are You maybe struggling trying to check steel class 4 member with commercially available softwares like Robobat Millennium, Ansys Civil Fem, Midas, Strand7, Abaqus, Sap 2000, and You are not satisfied by the way they consider distortional buckling, and its interaction with local and global buckling? 
If Yes, maybe You are interested in our CS4 software. Cs4 is designed to be a plug-in for your actual structural analysis software (provided that Your software house helps You a little bit).
CS4 is a postprocessor specifically designed for thin-walled steel or alluminium profiles, and properly considers in a very advanced and computationally elegant approach the effect of local, distortional and global instability typical of these members. Cs4 can design every kind of thin walled cross section (i.e. open, branched, closed), as shown in the image below (in this moment, only open sections are available in the stable release, all the others kind of sections will come in a very near future).
 

Cs4, as opposed to many available postprocessors, does not merely apply some "simplified" rules provided by codes to check the cross section or the whole member for resistance or stability: Cs4 also perform a stability analysis of the member in order to determine critical buckling load, properly taking into account local, distortional, lateral-torsional and generally speaking global buckling.
The theoretical base for Cs4 is the Generalized beam Theory (The GBT theory). Cs4 thus integrates computational stability analysis into the design process, an approach that is highly recommended by many experts. 
In fact, one can say that Cs4 performs a multi-scale analysis of the member: 
  • the large scale analysis is the global analysis of the structure performed by the software Cs4 is linked to (i.e. Ansys, Robobat Millennium, et cetera), 
  • the small scale is the stability analysis of the member (with local buckling and section distortion taken into account) performed by the GBT f.e. core of Cs4.
Cs4 lets You design very light and cost effective steel structures, made of thin Class 4 profiles.

In short terms CS4 is made for 
  • being easily linked to whatever structural analysis software, even that software that You can use better: Yours!

  • designing very slender thin walled steel members according to several national or international codes (for example EuroCodes) with a process based on a GBT stability analysis: The verification process.
If these points are of interest to You, and You also think that design of Cold Formed Members is possible,  please follow this site, or the HISTORY and NEWS page it is continuously updated!
