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.) and then proceed with the design. However, those that already use ETABS or SAP2000 can take advantage of the for ETABS or for SAP2000 versions. In that case, the program automatically extracts all the necessary data (geometry, member profile, loads etc.) from the model in ETABS or in SAP2000, with speed, accuracy and minimum effort. The GUI of all the applications in the EC PRAXIS Series is similar to that of ETABS, thus ensuring ease of use and speed. That way, even in the stand-alone version, an engineer can model a steel connection or a composite member and design it according to EC3 or EC4 in a very short time and most of all, reliably. The results of the design are presented in ready-to-print detailed reports in various formats (.rpt, .pdf, .xls, .doc, .rtf) which can be edited by the user. Additionally, in the case of steel connections, detailed drawings in .dxf format are automatically created. EC Praxis is is used for the design of composite beams and steel connections according to Eurocodes. It functions within an integrated environment that automatically extracts all the necessary data (geometry, member profile, loads etc.) from the model that has been previously created in ETABS or in SAP2000.
