Up until version 2023.b, the operations entered in the connection were accessed via the side list. In this version, quick access has also been provided by clicking on elements in the 3D view. Selecting elements in the 3D view will open the operation where the element is defined in the left panel.
Version 2023.b implements the detailed checking of anchors in accordance with Eurocode EN 1992. Until version 2023.b, the analysis of the connection was carried out by considering the anchors positioned and the non-linear contact between steel and concrete, but without checking the resistance of the anchors.
These new detailed checks can be consulted in the "Analysis" tab, as well as the checks already implemented for the rest of the elements. These checks can be for a single anchor as well as for the group.
In the project options, in the "Codes" dialogue box, the group of options relating to the concrete code for anchor testing has been implemented.
The "Anchors" operation includes the "Check anchors" option. When this option is activated, the program checks the anchors and also allows certain parameters and factors that must be taken into account in this check to be edited.
The connection summary list includes the resistance tables of the anchor group and the individual resistance of each anchor.
Eurocode 2 - Design of concrete structures - Part 4: Design of fastenings for use in concrete.
Implemented in CYPE Connect and StruBIM Steel for checking anchors in concrete.
"Building Code Requirements for Structural Concrete".
Implemented in CYPE Connect and StruBIM Steel for checking anchors in concrete.
Version 2023.a of the "CYPE Connect" and "StruBIM Steel" programs includes the analysis of the rotational stiffness of the connections. With this analysis option, users can obtain as results the resistant moment, initial stiffness, secant stiffness and classification of the connection (rigid, semi-rigid or pinned) of the steel section.
To obtain the "Moment - Rotation" graph, the program carries out an iterative process by analysing the rotation in different load steps. The resistant moment is obtained when any element in the connection (plates, sections, welds or bolts) no longer complies, i.e. its demand capacity ratio is greater than 100%.
The "Analysis" tab includes the "Rotational stiffness" tool in the top toolbar. If the tool is selected, the rotational stiffness analysis is run.
Furthermore, the "Analysis" tool has been renamed. In previous versions, the "Analysis" button was used to run the stress and deformed shape analysis. This button will now be called "Stress / Deformed shape".
The results can be viewed on the right-hand side of the "Analysis" tab. The top drop-down menu allows users to choose the type of results to be displayed, "Stress/Deformed shape" or "Rotational stiffness". By selecting "Rotational stiffness" the program displays two tables and the "Moment - Rotation" graph.
The first table shows all the analysed bars with their secant stiffness and the connection classification in each plane. The second table shows the load cases analysed for the selected bar. Each load case will indicate the acting moment, the resistant moment, the secant stiffness and the initial stiffness.
The graph shows the curves for "Moment - Rotation", "Acting moment of the selected load case", "Resistant moment", "Ultimate stiffness for rigid connections (Sj,1)" and "Ultimate stiffness for pinned connections (Sj,2)".
As a result of implementing the rotational stiffness analysis, the following changes have been made to existing tools in the program:
In version 2022.e, the importation of sections from the BIM model has been improved. It is now possible to select or modify the sections for each of the typologies defined in the IFC file.
In the "Bars" step of the BIM model import assistant, a list of detected section types is displayed. In the "Cross section" column, the section to be assigned in CYPE Connect will be indicated. By clicking on each cell, the cross section and material selection panel can be accessed.
When possible, the program generates a proposal based on the information available in the BIM model. Users can select the sections they wish to import as well as carry out manual assignments when deemed necessary or when automatic detection has not been possible. The assignment made is saved for subsequent imports.
The possibility of using the predefined section libraries that are available in other structure design software such as CYPECAD and CYPE 3D has been incorporated.
As of version 2022.e, users can select the load cases to be considered when analysing a joint. To do this, the "Acting" column has been added to the table in the "Load case" dialogue box, allowing the desired load cases in the analysis to be activated or deactivated.
Version 2022.d implements the analysis and checking of steel connections according to the following standard:
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.
"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.
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.
