Hollow structural section joints

Design of circular, square and rectangular hollow section joints.
Contains a large number of Design Codes of different countries (Eurocode, AISC, etc.), thousands of profiles of worldwide profile manufacturers with their corresponding steels and type of fabrication.
Generates detailed construction drawings and analysis reports for an excellent structural design project.
