CYPE Connect

Concrete anchors

As of version 2022.f of CYPE Connect and StruBIM Steel, users can now model and design elements anchored to concrete. To do this, the "Anchors" and "Concrete" features have been included for modelling the connection.

  • Anchors
    The "Anchors" feature allows users to introduce the anchor elements of a steel plate or section into a concrete block. The program allows users to design the connection given the geometrical layout of the fastenings, as well as their geometrical and mechanical properties. There is a choice of different types of anchors, either welded or bolted.

    The anchorage can be made either to a new concrete block defined in the operation itself or to an existing block that has been previously defined.
  • Concrete
    The "Concrete" feature allows users to enter a concrete block where the material, dimensions and position of the block are defined.
  • Analysis
    When the analysis is carried out, a finite element model is automatically generated that characterises the behaviour of the different components involved in the connection, considering the type of anchors and the properties of the concrete block. Once the analysis has been completed, the compressive strengths in the concrete can be checked. The anchors cannot yet be checked in version 2022.f, but their resulting forces can be consulted.

Bar section information

Information about section geometry has been implemented in the label of the bars, where previously only the reference was shown.

Clash checking between plates and sections

Clash checking between plates and sections has been implemented. The mid surface of the plates or parts of the sections is checked to ensure that they do not intersect with another plate or section. This check is necessary to avoid inappropriate analytical models.

Structural timber element connections

As of version 2022.d, CYPE Connect can model and analyse connections between structural timber elements as well as steel-to-timber elements.

The new CYPE Connect feature makes designing steel-to-timber connections easier. In these connections, forces are transmitted from one piece of timber to another by means of metal elements (fasteners and connections). The connection between the different structural timber elements is achieved by means of dowel-type fasteners and auxiliary steel elements such as metal sheets or sections. The timber elements transmit their forces via the fasteners (bolts, dowels and screws) to all the other elements they are connected to (steel sections and sheets).

For modelling timber connections, the "Timber" operation has been implemented in the editing screen of a connection, which includes the tools "Bolts", "Dowels" and "Screws". In the rest of the operations available in the top bar of the program, the necessary modifications have been implemented for considering timber elements depending on the requirements of each operation.

After defining all the elements that make up the connection, the calculation can be carried out following the same procedure as for connections between steel sections.

The program analyses the stresses and deformations of each of the connection components using OpenSees© finite element software. With the acquired results, besides checking the steel elements in accordance with the selected steel code, the fasteners for timber are also checked according to the criteria in the chosen timber code.

For mechanical connections, dowel-type elements are an essential part of the load-bearing structure. By checking these fasteners in accordance with the requirements in the timber standard, we ensure that they are correctly designed to withstand and transmit the forces they will be subjected to. In version 2022.d, the criteria of Eurocode 5 (EN 1995-1-1) have been implemented.

In order for CYPE Connect to be able to model and analyse connections between structural timber elements, the user license must have the corresponding permission. For steel-to-timber connections, the user license must have permissions for both connection types. In any case, the OpenSees© calculation engine user license permission is required.

Change in program name

CYPE Connect Steel is changing its name to CYPE Connect.

The reason for this change is that in previous versions, CYPE Connect Steel carried out the modelling and analysis of steel structural connections. As of version 2022.d, the program can also model and analyse structural timber elements as well as steel-to-timber connections.

IS 800: 2007 (India)

"Indian Standard. General construction in steel - Code of practice"

Implemented in CYPE Connect (CYPE Connect Steel) and StruBIM Steel for analysing and checking steel connections.

3D view of check results

The "Export 3D view of the check results" option has been added to the "Share" dialogue box that opens when exporting to BIMserver.center.

When exporting with this option activated, a 3D view will be generated in which elements are coloured according to their demand capacity ratio, as well as including this ratio in the associated information.

Improvements in the "Adjust section" tool

Two options have been implemented for adjusting a section or end plate "To the nearest face" or "To the furthest face" of sections. Up until version 2022.c, the part of the section we wished to adjust or connect (depending on the operation) had to be selected. With the new implemented options, the program will automatically detect the face.

 

Material, section and bolt libraries typically used in Brazil and the United Kingdom

Version 2022.c implements the design and checking of connections in accordance with the following codes:

  • ABNT NBR 8800:2008 (Brazil)
    "Projeto de estruturas de aço e de estruturas mistas de aço e concreto de edifícios".

  • BS 5950-1 (United Kingdom)
    "Structural use of steelwork in building. Part 1".

  • Código Estructural (Spain)
    "Código Estructural (Real Decreto 470/2021)".

Along with the implementation of the Brazilian and UK codes, libraries including materials, sections and bolts typically used in Brazil and the United Kingdom have been added.
