Perimeter weld

The "Adjust bar" and "End plate" operations include a new option when defining welds: the choice between perimeter welding or parametric welding. Up until version 2024.f, welds were always placed parametrically on wings and webs, depending on the type of section.

The new perimeter welding option will add welds along the entire contact area between the selected elements. For circular hollow sections, the weld must always be a perimeter type.

Perimeter welds shall be shown on the drawings with their corresponding symbols.

Improved finite element model of the bars

In version 2024.f, changes have been implemented in the finite element model of the connections compared to previous versions.

For the stress/strain analysis, the new model incorporates an additional extension of the bars, which consists of a linear elastic plate system and a reduced number of elements.

The extension allows users to consider the effect of modelling bars with a longer length, without penalising the analysis time.

The end nodes of each bar are bound with rigid links to apply loads or restrictions, which implied that the end section of each bar was considered to be non-deformable. In some cases, this assumption could lead to stress concentrations at the ends, or to less conservative results.

With the new model, the non-deformable section is moved away from the connection to the end of the additional extension to avoid these issues.

This additional extension is neither represented in the connection modelling tab nor in the results tab.

New operation. Plate stiffeners - Circular hollow section

In version 2024.f a new operation is implemented to add stiffeners between a plate and a circular hollow section. The stiffeners are arranged around the circular hollow section radially and parallel to the section axis.

As well as the geometry of the stiffeners, users can define the number of these plates, which will be evenly distributed from an initial angle, around the user-defined angle. The point of origin of the initial angle coincides with the y-axis of the section.

Radial bolt generating tool

As of version 2024.f, the bolt and screw position table includes a new option to generate bolts radially by defining the number of bolts and the radius.

Circular plate

Up until version 2024.f, a circular plate could be defined by using the "Polygonal" option to create 2 or more curved sections.

As of version 2024.f, the "Plate" operation includes the new "Circular" option.

This new option allows users to define a circular plate more easily.

Importing the forces of circular hollow sections

Up until version 2024.f, circular hollow sections only imported their forces if they had been defined as reinforced sections.

As of version 2024.f, the forces of both reinforced hollow sections and circular hollow sections will be imported.

Improved CYPE 3D communication with StruBIM Steel and CYPE Connect

Up to version 2024.e, the import of CYPE 3D structures into StruBIM Steel or CYPE Connect was carried out from an IFC generated by CYPE 3D.

With this improvement in version 2024.f, this communication will be carried out by exporting and importing an exchange file in JSON format, which will allow more efficient communication and accurately reflect the specific features of a CYPE 3D structure.

Circular hollow sections

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.
