Using the “Composite steel and concrete columns” module, CYPECAD and CYPE 3D can check composite steel and concrete columns in accordance with the “EN 1994-1-1” and “ANSI/AISC 360-10” codes.
The code to be used for the composite column check is not selected directly as is done with the concrete and steel codes. The program applies a code depending on the selected concrete code.
Below are the implemented types of composite columns:
- Rectangular section with encased section
Always includes longitudinal and transverse reinforcement. - Rolled steel plate box section, filled with concrete
It is possible to include longitudinal and transverse reinforcement, and an encased steel section. - Cold-formed rectangular hollow section, filled with concrete
It is possible to include longitudinal and transverse reinforcement, and an encased steel section. - Cold-formed square hollow section, filled with concrete
It is possible to include longitudinal and transverse reinforcement, and an encased steel section. - Circular column with encased section
Always includes longitudinal and transverse reinforcement. - Cold-formed circular hollow section, filled with concrete
It is possible to include longitudinal and transverse reinforcement, and an encased steel section.
More information on this new CYPECAD and CYPE 3D module can be found on the Composite steel and concrete columns webpage.
