As of version 2024.f, the possibility to model and analyse connections between circular hollow sections in CYPE Connect and StruBIM Steel has been implemented.
In CYPE Connect, the node editing panel includes the option to select circular hollow sections within the hollow sections option.
In the connection editing panel, the existing operations adapt their use to work with hollow sections:
- Adjust bar
Allows users to adjust and weld bars to circular hollow sections. Each bar can have more than one adjustment at its ends, whether they are adjustments to planes defined by sections or plates, or adjustments to circular hollow sections.
- Trim plate
Allows a plate to be cut out of a hollow section and welds to be added between the plate and the hollow section. The hollow section can create an inner opening in the plate, or an outer trim, thus modifying the perimeter of the plate.
- Weld
Welds between circular hollow sections, or between circular hollow sections and plates have to be defined in the "Adjust bar" and "Trim plate" operations if the hollow section cuts the plate. From the "Weld" operation, users can add welds between plates and circular hollow sections in cases where any edge of the plate is parallel to the longitudinal axis of the hollow section.
The setting of the number of sides for the discretisation of the circular hollow sections can be found under "Modelling options". A user value or a value calculated automatically by the program can be defined.
Tubular hollow sections with a circular section are discretised by means of quadrilaterals and the number of elements can be reduced, thus reducing the analysis time.
