Improved design and checking of beams and columns with the Spanish structural code "Código estructural" and the Eurocodes

Two options ("Slope angle of the compression struts" and "Tolerances in spacing checks") and several improvements have been implemented in order to optimise the check and design of beams and columns. These options and improvements are available for the following codes:

Eurocode 2 (EU)
Eurocode 2 (Spain)
Eurocode 2 (Portugal)
Eurocode 2 (France)
Eurocode 2 (Romania)
Eurocode 2 (Malaysia)
Eurocode 2 (Singapore)
Código Estructural (Spain)

These new options can be accessed via the “General data” panel:

General data > Bars > By position > Options for columns, shear walls, walls and corbels > Design / Code checks.
General data > Bars > By position > Beam options > Design / Code checks.

The new options and improvements are detailed below:

Slope angle of the compression struts
Allows the angle between the compressed concrete struts and the longitudinal axis to be defined, which is to be considered in the shear resistance analysis. The program allows users to assign one general slope angle for the struts in all the columns of the structure, and another one for all the beams of the structure.

Values can also be assigned individually to columns and beams using the following options:

For columns
Column definition tab > Columns, shear walls and starts menu > Slope angle of the compression struts.

For beams
Beam definition tab > Beams menu > Other options > Assign the slope angle of the compression struts.

Tolerances in spacing checks
The “Tolerances in spacing checks” option has been added for beams and columns. This option allows the value of the tolerance that is permitted when carrying out the minimum and maximum spacing checks between reinforcement bars to be defined. If the difference in absolute value between the value required by the code and the calculated value is less than the tolerance considered, the check is compliant.

Analysis of the spacing between transverse reinforcement crossties
The analysis of the spacing between transverse reinforcement crossties has been improved.

Analysis of the concrete area for circular composite columns with embedded sections
The analysis of the concrete area for circular composite columns with embedded sections has been improved. The radius of the circular concrete section is taken as the minimum value between "the actual section radius" and "the maximum radius permitted by the code", which defines limits for the maximum thickness of the concrete cover in fully embedded sections.

Beam intersections references

The “Beam intersections references” option has been added to the “Groups” menu of the “Beam definition” and “Results” tabs. These references can now be generated automatically according to the order of the frames.

For jobs created from version 2023.a onwards, this will be the default option. For jobs that have already been created, the order in which they were generated is maintained, but the "Beam intersections references" option can be used to change the order.

Exporting the rebars of shear walls and stairs to the BIM model

The rebars of shear walls and stairs can now be exported to the BIM model.

In the current version of the program, CYPECAD exports the reinforcement of the following types of elements:

Concrete walls
Columns
Shear walls
Beam frames
Stairs
Foundation elements (footings, pile caps, strap beams and tie beams)
Slabs (waffle slabs, joist floor slabs, hollow core plate floor slabs, composite slabs and flat slabs)
Corbels

This reinforcement can be viewed in the StruBIM Rebar program along with the reinforcement exported from StruBIM Shear Walls.

They can also be viewed in CYPECAD in the "Results" tab (Groups menu > 3D view with details).

Automatic import of structural walls from a BIM project

As of version 2023.a, structural walls defined in a BIM project can be imported. This option is available both for projects modelled using our CYPE Architecture tool and for projects created with other BIM modellers.

Exporting in FBX format

Version 2023.a of all CYPE programs that have the "Print/Save the current view" tool (usually all programs that display graphic information in a window) allows any generated 3D model to be exported in FBX format. This is one of the most common and accepted formats among rendering software (Twinmotion, Enscape, Sketchup+Vray, among others).

Exportation in FBX format is found in the dialogue box that opens when selecting the "Print/Save the Current View" button in any of the programs that include this tool. This feature allows users to export any element that is visible in the current window at that moment in FBX format (as well as elements that have been imported from other programs).

"Channel with stiffened web" type in BS 5950-5:1998 cold formed steel sections

In version 2022.e, "Channel with stiffened web" type cold formed steel sections have been included for beams and columns (CYPECAD) and for bars (CYPE 3D) when the selected standard is BS 5950-5:1998.

Other improvements and corrections

Version 2022.e of CYPECAD includes other minor improvements and corrections of the program for certain cases:

Final design report
In the final design report, warnings concerning concrete wall checks have been added.
Checking the results of wall openings
An error that occurred when checking the results for wall openings when these were defined on a floor with continuous reinforcement has been fixed.
Editing frames
When editing beam frames, the possibility to define "Length with straight extension" in "Longitudinal reinforcement > Edit hooks" has been added.
Checking fire resistance
An error that could sometimes occur when checking a series of steel sections in beam frames, when checking fire resistance, has been fixed.
Sharing in BIMserver.center
The "BIMserver.center > Share" option panel has been improved, it was not displayed correctly at times when the screen resolution is small.
Sharing in BIMserver.center
An error that could occur in the "BIMserver.center > Share" option when generating the reinforcement for column starts has been fixed.
Punching shear check
An error that occurred in the punching shear check process when there is a mat foundation with a very small surface in contact with a column has been fixed.
Deleting or dividing groups
An error that occurred when deleting or dividing a group in the case of walls with blocked reinforcement has been fixed.
Beams information
An error that occurred when selecting a wall that starts on top of another wall in the "Information - Beams" option has been fixed.
Bills of quantities
The measuring of formwork for beams in the "Bills of quantities" option has been improved. In some cases, an element with a 0 m2 surface was added.
Changing a job’s code (EHE-08 to Código Estructural)
The transformation of a job initially created with code EHE-08 when it is updated to code "Código Estructural" has been improved. As well as adapting the "Environment" selection in "General data", it is adapted in each beam that has a specific assignment.
Checking the baseline shear
The checking of the base shear for walls without external fixity in contact with column starts with external fixity has been improved.
Checking geometry
An error that occurred in the "Check the geometry of the current group" and "Check the geometry of the current group and higher groups" options, if sloped beams had been introduced in the job, has been fixed.
Analytical model
An error that could sometimes occur when obtaining the analytical model of a wall whose axis did not match the centre and that ended in a sloped slab has been fixed.
Assign walls
The "Assign walls" option has been improved in order to consider embedded or crown beams with specific features.

Creating construction details with an image

In the "Add user information" option (Drawing editor - Details – Add user information), details can be created by importing an image. Up until the previous version (2022.d), details could only be created from DXF and DWG files. In the import process, the final size of the image in the drawing can be defined.

Spanish structural code "Código Estructural"

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

Implemented in CYPECAD and CYPE 3D for analysing and checking composite concrete and steel columns.

Linking to BIMserver.center

As of version 2022.e, applications that are connected to BIMserver.center communicate with the platform more directly. As a result, it is no longer necessary to specify the user account(s) and projects to be synchronised in the BIMserver.center Sync tool before using the applications. When a user signs in from a desktop application, it automatically establishes the connection to the project.

Previously, some applications required the user to connect to BIMserver.center and select a project in order to start a job. Now, this is no longer necessary and the link will only need to be established when updating the project or sharing a contribution.

BIMserver.center project status

As of version 2022.e, the applications connected to BIMserver.center have an information bar displaying the link status to the project on the platform. This bar can be found at the top right of the application window and is divided into the following sections:

User
Displays the BIMserver.center user name that has been entered to access the application. If a connection has not been established with a platform user, the text "Connect" will appear. If the user clicks on this button, they will be able to type in their name and password, as well as sign out in order to access with other login credentials.

Project
Displays the name of the BIMserver.center project linked to the job, if such a link exists. By clicking on this button, we can obtain additional information about the project, such as its description, project type or view options. If any warnings or errors occur when uploading or downloading contributions to the project, a list will be displayed in this panel with all the incidents detected. Furthermore, the project icon in the bar will change to a warning symbol.

Status

Displays the status of the connection with BIMserver.center.

When a contribution is being uploaded or downloaded, the text of the message changes and the progress of the action is displayed.

If an older version of the BIMserver.center Sync synchronisation tool is running, the message "Incompatible version of the BIMserver.center synchroniser" is displayed.

The synchroniser can be downloaded and installed free of charge from the BIMserver.center platform or installed during the installation process of the applications. The latest version of the tool is required for applications to be able to display status messages.
