As part of its continuing effort to provide civil engineers with reliable, accurate and versatile software, CSI Hellas has developed a family of applications for the design of steel connections and composite members according to EC3 and EC4, respectively. The various applications are available in two different versions, depending on whether or not they can integrate with ETABS or SAP2000. In the stand-alone version, the user must input all the relevant data (geometry, member profiles, loads etc.)
