New modules and programs

Open BIM Suspended ceilings (new program)

Open BIM Suspended ceilings is a free program created to design suspended ceilings of any type of building. It generates the layout of the suspended ceilings, which provides a valuable aid in their subsequent installation in the different rooms.

The program allows users to create a library of types of panels, it has a tool to automatically distribute the layout of the suspended ceilings, but also allows for them to be introduced manually, which is helpful for special cases.

An important aspect when carrying out the layout of the suspended ceilings is to locate where elements such as lights, air conditioning inlet and outlets or holes of the sprinkler system will be placed. Since "Open BIM Suspended ceilings" is integrated into the Open BIM workflow, it is able to read the requirements of openings of other programs included in that workflow, to include them in the final layout of the project. Furthermore, these programs, will also read the layout of the suspended ceilings provided by "Open BIM Suspended ceilings", which will allow them to visualize the panels and correctly place the elements.

"Open BIM Suspended ceilings" also generates the materials schedule of the suspended ceilings that have been placed and their quantities (including the calculation of the percentage loss of cut panels and holes) to export them to FIEBDC-3 format, that can be read by programs that manage bills of quantities.

Open BIM Suspended ceilings can be downloaded from the BIMserver.center platform.

More information on this new CYPE Open BIM program will be available shortly.

Post-tensioned waffle and joist floor slabs (CYPECAD module)

The CYPECAD module: "Post-tensioned waffle and joist floor slabs" allows users to design the passive reinforcement of waffle slabs, in-situ joist floor slabs and their perimeter beams, after calculating the forces of the post-tensioned tendons (adherent or non-adherent) and whose properties have been introduced by users.

This module allows users to introduce the layout of the tendons, their definition, stressing loads and percentage losses (instantaneous and deferred). The program generates two post-tensioned loadcases (one with instantaneous losses and the other with total losses: instantaneous + deferred) in which it will introduce the deviation loads that are produced due to the path of the tendons.

During the reinforcement design phase of the waffle slabs and, if the tendons have been defined as adherent, the contribution of the remaining or excess capacity of the active reinforcement is taken into account, which is subtracted to determine the passive reinforcement.

The functionality of the tools for introducing and editing bending lines and tendons is the same as for Post-tensioned slabs for building.

In order for CYPECAD to be able to carry out the indicated calculations for post-tensioned waffle slabs and joist floor slabs, the user license must include the permits for the “Post-tensioned waffle slabs and joist floor slabs” module.

StruBIM Anchors ACI 318 (new program)

StruBIM Anchors ACI 318 is a program designed to check concrete element anchors based on the ACI regulation (ACI 318-11 Annex D or ACI 318-14 Article 17). It checks cast-in, headed bolt anchors, L-bolt, J-bolt and bolts with their head welded to the plate, as well as post-installed anchors such as adhered anchors, undercut anchors, torque-controlled anchors with sleeves and headed stud anchors, and displacement-controlled anchors.

This application is integrated in the Open BIM workflow using the IFC standard. The program currently provides an IFC file to the BIM model that includes the check reports in PDF format.

StruBIM Anchors ACI 318 can be downloaded from the BIMserver.center platform.

CYPE Health and safety (new program)

CYPE Health and safety is a program created to assist users in the development of drawings of collective protection elements to be incorporated in the Health and Safety Project. It also exports the quantities of the introduced elements in FIEBDC-3 format to be treated by bill of quantity management programs.

With "CYPE Health and safety" users can define the construction phases of the project and include collective protection systems in each of them. The program allows users to define the following collective protection systems:

Railings and railing supports
Vertical nets and gibbet type supports
Floor slab openings protection
Storage zone
Risk indicator signs
Perimeter fence
Excavations
Accesses

CYPE Health and safety is integrated into the Open BIM workflow through the IFC standard. To be able to work with it, the project must be linked to a BIM project and the program will import the floor structure to generate a floor plan for each floor that has been imported from the project. In each floor plan, users must draw the safety elements that are to be included in the project.

To be able to work with CYPE Health and safety, users must have the required permits, which are the same that are required to access the "Collective protection systems" module of CYPECAD. This permit must be updated to the 2019.a version or later.

CYPE Health and safety can be downloaded from the BIMserver.center platform.

More information on this new CYPE Open BIM program will be available shortly.

Open BIM Switchboard (new program)

Open BIM Switchboard has been created to design the enclosures that are present in electrical installations (cabinets, panels, switchboards...).

In previous versions, CYPELEC REBT (Spain) and CYPELEC NF (France) contained tools to design these enclosures in the “Cuadros” and “Tableaux” tabs, respectively. As of the 2019.a version, these tabs have been eliminated from the aforementioned programs and have been implemented in “Open BIM Switchboard”.

In comparison to the “Cuadros” and “Tableaux” tabs of the previous CYPELEC REBT and CYPELEC NF versions, Open BIM Switchboard has the advantage of being integrated in the Open BIM workflow and the possibility to be used by users from other countries, since the program can be installed in English, French, Italian, Spanish, Catalan and Portuguese, and has an Open BIM connection with CYPELEC Core as well as with CYPELEC REBT and CYPELEC NF.

To begin working with Open BIM Switchboard, users must be connected to a previously created BIM model. The program imports the geometry of the building from the BIM model, if it exists in the model, and that has been generated and included in the model by CAD/BIM programs such as IFC Builder, Allplan, Archicad or Revit using IFC files.

Additionally, if programs such as CYPELEC Core, CYPELEC NF and CYPELEC REBT have included IFC files of the single-line diagram of the installation in the BIM model, Open BIM Switchboard will import the panels and subpanels of the installation, together with their switchgear (including any busbars and bridge lines that have been defined). If, additionally, in the indicated CYPELC programs, the enclosures of the installation have been placed in the "Floor plans" tab, their position will also be imported. In this case, the designer must only define the box or cabinet that will contain the switchgear of each enclosure and position the switchgear, which has already been calculated by CYPELEC Core, CYPELEC NF or CYPELEC REBT, inside it.

The position of the envelopes that is imported from CYPELEC programs is represented in the 3D view by a generic three-dimensional element. When users define the real dimensions of the envelopes in CYPELEC, they will not coincide with the generic element. The two elements that are displayed in the 3D view and can be activated or deactivated from the view separately. In Open BIM Switchboard, the position of the envelopes that have been imported from the BIM model can also be modified.

The Open BIM connection of "Open BIM Switchboard" with CYPELEC programs allows the project designer to greatly speed up the design process of the electrical panels. Nonetheless, Open BIM Switchboard allows users to design the envelopes from scratch. That is, there is no need for the geometric information of the building or the information of the switchgear that has been calculated in CYPELEC programs, to exist in the BIM model.

The operation of "Open BIM Switchboard" is the same as that of the "Cuadros" tab of CYPELEC REBT and "Tableaux" of CYPELEC NF.

Open BIM Switchboard can be downloaded from the BIMserver.center platform.

To be able to work with “Open BIM Switchboard”, users must have the corresponding license permit, which is the same as that required in previous versions to access the “Design of electrical panels” module of CYPELEC REBT and CYPELEC NF.

More information on this new CYPE Open BIM program will be available shortly.

CYPE Lightning (new program)

CYPE Lightning is a free application designed to carry out the 3D layout of the elements of a lightning safety installation in any type of building, complying with the requirements imposed by users.

The program calculates, verifies and describes the safety installation including all the elements it consists of: ESE type lightning rod (early streamer emission lightning conductor), boxes with their respective grounding connections, connections with metal elements on façades and with receiver sets (antennas), grounding conductors, etc. The program, additionally, generate documents and relevant drawings to justify the lightning protection installation.

"CYPE Lightning" is integrated in the Open BIM workflow using the IFC standard. The program imports the geometry of the building from the BIM model (generated by CAD/BIM programs such as IFC Builder, Allplan, Archicad or Revit) and, if the risk level of the project has been evaluated with the "Open BIM CTE SUA 8" application, the value of the distance to the centre of the fictitious sphere, D, which describes the protection volume of the ESE, can be obtained from the BIM project.

Furthermore, "CYPE Lightning" exports an IFC file to the BIM model, containing the document that justifies the standard (.pdf). It also generates two independent 3D files (.gltf) to be able to view the lightning protection installation, as well as the properties of each element, and the protection volume in the web viewer of the BIMserver.center platform.

CYPE Lightning can be downloaded from the BIMserver.center platform.

More information on this new CYPE Open BIM program will be available shortly.

CYPETHERM Schematics (new program)

CYPETHERM Schematics is a free program designed to draw the circuit diagrams of hydronic air conditioning systems. The components are represented using symbols in accordance with ASHRAE standards.

In previous versions, CYPETHERM HVAC was the program that provided the tools to draw these diagrams in the “Circuit diagrams” tab. As of the 2019.a version, these tools have been removed from CYPETHERM HVAC to be implemented in the new "CYPETHERM Schematics" application. The design process of pipes that was carried out in the "Circuit diagrams" tab is still done in CYPETHERM HVAC.

CYPETHERM Schematics is not just a tool for drawing circuit diagrams. It has important advantages compared to conventional drawing programs and these are:

Iconography
The iconography of the valves corresponds to ASHRAE standards, which avoids users from having to create their own drawings with the associated risk of using local representations that are not regulated.
Quantities
All the elements are entities with associated properties, and appear in the quantities.
Equipment calculations
Some elements have an internal calculation in the properties panel to help users design the equipment, for example, the expansion vessel, the air conditioners (or air treatment units) and generic fan-coils, and pipes. These calculations have an associated justification report, where the calculation is explained as well as the associated standard.

CYPETHERM Schematics is integrated in the Open BIM workflow using the IFC standard. It exports the documents containing information on the circuit diagrams of the included equipment to the BIM model.

CYPETHERM Schematics can be downloaded from the BIMserver.center platform.

IFC Builder

Architectural element information in the 3D viewer of BIMserver.center

As of the 2019.a version IFC Builder includes data on the geometric model in the file in "gltf" format, which is used to display the 3D model in the web viewer of the BIMserver.center platform. Thanks to this new feature, BIM project collaborators will be able to obtain the following information regarding the construction elements of the project:

Façades, party walls, partitions, basement walls, screeds, floor slabs and roofs.
- Reference of the type
- Thickness
Doors, external carpentry and glazed openings
- Reference of the type
- Width
- Height
Skylights
- Reference of the type
Nearby buildings and other obstacles
- Height

Multi-instance

The possibility of opening IFC Builder several times simultaneously has been implemented, so users may work on several projects at the same time. This option was already available for other CYPE applications.

CYPECAD / CYPE 3D

Steel library for user-defined sections

In the 2019.a version of CYPECAD and CYPE 3D, users can now define steels for which they can indicate their elastic limit. The modulus of elasticity, thermal expansion coefficient, density and Poisson's ratio are defined internally by the program using the values of the steel. For U.L.S. checklists, the type of steel that is used can be seen.

As well as the elastic limit and depending on the selected code, additional data may be required to design connections.

The user steel library can be accessed from General Data. Rolled or cold-formed steel can be assigned to the sections as can steels that are established by each standard.

User-defined steels can be exported to the library to be used in other projects. They can also be selected as initial steels for the creation of new projects. The library is common to CYPECAD and CYPE 3D.

In CYPECAD:

In CYPE 3D

Effects of the vertical seismic component

As of the 2019.a version, CYPECAD and CYPE 3D can take into account the effects of the vertical seismic component by considering them as a percentage of the gravitational effect. Optionally, both programs apply a modification or adjustment coefficient that acts as the sum of the factor of the permanent loads in the seismic force combinations.

This coefficient increases the factor of the permanent loads in seismic combinations for unfavourable gravitational conditions and decreases the factor of the permanent loads for favourable gravitational conditions. In the first case, the gravitational effects are added to the seismic effects. In the latter, the gravitational effects counteract the seismic effects.

Consideration of the effects of the vertical seismic component

In building design, it is usual to calculate a structure to against the horizontal action of the earthquake and neglect the effects of the vertical component. However, in certain cases, it is advisable to consider these effects in the design.

CYPECAD and CYPE 3D apply an alternative procedure to the specification of spectra to consider the vertical seismic action, including its effects in seismic combinations by increasing the effect of the permanent load. This increase takes positive and negative values, due to the reversibility of the seismic action, and increases and decreases the gravitational effects in the combination. By doing so, the effects of vertical movement of the floor in buildings are simulated, such as:

The variance of the axial force in elements that resist vertical loads.
The variance in the localised deformation at the top of columns and the deflection at floor slab mid-spans.
The variance of the total vertical shear force that is transferred between floor slabs and columns.

CYPECAD and CYPE 3D propose a simple calculation for this modification coefficient, which provides a value that adapts to what is established in the standards and that is a function of the seismicity of the site that has been selected by the user. Some codes call it "vertical seismic pseudo-acceleration", but it does not represent the total vertical response, only the part that is combined with the horizontal response and the effects of gravity. The data proposed by the program can be modified by users, since different situations to those usually contemplated by the standards may arise.

In the section of the seismic data dialogue where users can activate whether or not the effects of the vertical seismic component are to be considered, there is a help button where more information on the calculation of the "vertical seismic pseudo-acceleration" coefficient can be found.

CYPECAD

Block foundation elements

As of the 2019.a version, it is possible to block the dimensions and reinforcement of footings, pile caps, and strap and tie beams so that they do not undergo any changes during the foundation design process.

The “Block/Unblock” option has been implemented in the “Foundation” menu of the “Beam Definition” and “Results” tab. When selected, users can choose which elements are to be blocked or unblocked. The option to block or unblock is also available in the “Foundation elements” editing window (footings and pile caps) and “Strap and tie beams”.

Column and wall distortions report

As of the 2019.a version, the “Column distortions” report is called “Column and wall distortions”. This report, in previous versions, only included column distortions. As of this version, the distortions of walls connected to the rigid diaphragm of the floor also appear in the report.

Worst case element in maximum value tables of the distortions report

The tables containing the maximum values in the “Column and wall distortions” report include, as of the 2019.a version, the worst case element to which the value corresponds.

Summary, by group, of reinforcement quantities, by diameter

As of the 2019.a version, the “Reinforcement quantities, by diameter” report can show the reinforcement by diameter summary, by group.

Export data to the BIM model for “CYPE Memorias CTE”

As of the 2019.a version, CYPECAD projects that are connected to a BIM model of the BIMserver.center platform allow for the necessary information to be exported to create the "Structural security" and "Security in case of fire - SI 6" sections of the Project report with the CYPE Memorias CTE program, which has also been implemented in this version.

Move columns connected to beams and introduce new columns

Since the 2018.h version, when a column that is connected to beams on a floor is moved, the beams do not move automatically with the column. Neither are the beams reorganized when a new column is introduced and cuts existing beams. Due to this, the intersections between columns and beams must be recreated when columns are added or moved.

As of version 2019.a the program asks a question, and users can choose to either automatically recreate the intersections or to take no automatic action (in which case, users will manually recreate the beam-column intersections afterwards). Depending on the complexity, it is possible that the program will not be able to automatically resolve certain intersections, and so the program will warn of invalid results.

Block plane stress wall reinforcement

As of the 2019.a version, users can use the option “Block reinforced concrete wall reinforcement” (“Results” > “Beams/Walls”) to also select and block the reinforcement of plane stress concrete walls.

F6 key to activate and deactivate load visibility

The “Visible loads” option can be accessed using the F6 key. Using this option, the visibility of the loads can be activated or deactivated.

“Columns, shear walls and starts” and “Floors/Groups” menus in floating windows

The “Columns, shear walls and walls” and “Floors/Groups” menus in the “Column Definition” tab opens as a floating window to access the options it contains more easily whilst users are working with them.

Access to the “Forms” menu from the “Results” tab

The “Forms” menu, which could be accessed as of previous versions from the “Panels” drop-down menu in the “Beam Definition” tab, is also available in the “Slab/Waffle slabs” drop-down menu in the “Results tab”.

Edit torsional stiffness reduction coefficients for steel and timber beams

Since previous versions, torsional stiffness reduction coefficients can be defined for concrete beams. As of the 2019.a version, it is also possible to reduce the torsional stiffness for steel beams and timber beams. These coefficients can be edited in the "Torsional stiffness reduction coefficients" dialogue (Project > General options > Torsional stiffness reduction coefficients).

Update line loads of construction elements and post-tensioned tendons

The option “Update line loads of construction elements and post-tensioned tendons” has been implemented in the “Loads” menu in the “Beam Definition” tab.

As of previous versions, the program calculates the line loads of construction elements ( “Beam Definition” tab > "Loads" menu > "Construction elements" option) and post-tensioned tendons ("Beam Definition" tab > "Post-tensioned" menu). If changes were made in these elements or in others related to them that could affect self-weight values, the program did not recalculate the loads until the project was analysed or until drawings or reports were obtained.

As of the 2019.a version, when users select the new option: “Update the loads of construction elements and tendons”, recalculates the aforementioned loads, which allows users to view their values on-screen after the modifications have been made, without the need of having to analyse the project or print drawings or reports.

Null self-weight for timber floor slabs

Timber floor slabs can be assigned a null self-weight value.

Ungrouped column schedule

As of the 2019.a version, the Column schedule can be displayed showing the column groups defined in “Results” or ungrouped, in which case each column will be displayed in a column of the schedule.
