Using the “Composite steel and concrete columns”, CYPECAD and CYPE 3D design composite steel and concrete columns composed of rectangular or circular concrete columns with an encased steel section, Rolled steel plate box sections, filled with concrete; rectangular, square and circular hollow sections filled with concrete.
Using the “Composite steel and concrete columns” module, CYPECAD and CYPE 3D can check composite steel and concrete columns composed of a rectangular or circular concrete section with an encased section; rolled steel plate box sections, filled with concrete; and cold-formed steel rectangular, square or circular hollow sections, filled with concrete.
CYPECAD allows users to define, for each column that is introduced, specific values for the following parameters during its introduction (whose values are defined in the general data of the job or in the analysis options):
In CYPE 3D, these properties are defined using different options in the Bar menu.
In CYPECAD, when introducing the data, the fixed point of the columns can be defined (at corners or faces) for when the section size of a column varies from one floor to another. In CYPE 3D, the fixed point is defined using the “Describe disposition” option in the “Bar” menu.
Columns introduced in CYPECAD and in CYPE 3D must be vertical. CYPECAD does not allow for them to be introduced any other way, however in CYPE 3D, users could define a bar, as being a column-type structural element, whose local X-axis is at an angle with respect to the global Z-axis. In these cases, CYPE 3D marks the bar as containing an error (if the “Show/Hide incidents” option in the “Analysis” menu has been activated) with the following message: “The element must be vertical, with its local X-axis in the ascending direction”. The program does not allow for the structure to be analysed (and also displays this problem if the analysis is launched regardless of whether the “Show/Hide incidents” option has been activated or not) until the direction of the local X-axis of the bar does not coincide with that of the global Z-axis.
CYPECAD and CYPE 3D check the following types of composite columns:
CYPECAD and CYPE 3D check the types of columns indicated in the previous section, in accordance with the following codes:
The code for the design of composite columns is not selected directly as is done with the concrete or steel codes. The program uses either the “EN 1994-1-1” code or the “ANSI/AISC 360-10” code depending on the concrete code that has been selected. Furthermore, bear in mind that CYPECAD and CYPE 3D can only check composite columns when the selected concrete code is implemented in the Advanced column editor.
The EN 1994-1-1 code will be used by CYPECAD and CYPE 3D to check composite columns when the concrete code is one of the following:
The “ANSI/AISC 360-10” code will be used by CYPECAD and CYPE 3D to check composite columns when the concrete code is one of the following:
CYPECAD and CYPE 3D have an advanced column editor (for concrete, steel and composite columns), which allows users to:
More information on this tool, available for CYPECAD and CYPE 3D, can be found in the “Advanced column editor” webpage.
For CYPECAD or CYPE 3D to be able to design composite steel and concrete columns, users must have the required permits to be able to use either program and the “Composite steel and concrete columns” module (used by both CYPECAD and CYPE 3D).
CYPECAD is available in its unlimited version and also in two limited versions called LT30 and LT50, which contain the same tools and module acquisition possibilities, but have the following conditions:
Integrated 3D structures of CYPECAD (also LT50 and LT30) is not technically a module. To define these 3D structures in CYPECAD, users must also have the required permits to use CYPE 3D in their user license and, optionally, modules which are exclusive to CYPE 3D.
The following modules are those that can be acquired together with CYPECAD or CYPECAD LT:
