In the “Flat, waffle and joist floor slab options” - “Punching shear” (“Project” menu > “General data” > steel bars “By position” button), the difference between the top surfaces of the floor slabs can be defined in order to carry out the punching shear check in the same way as if they were at the same level. If the distance between the top surfaces of the floor slabs facing the support is greater than the defined value, the punching shear checks will not be carried out.

Other improvements and corrections
Version 2022.g of CYPECAD includes other minor improvements and corrections of the program that could occur in certain cases:
- Improvement in the “Forces in columns, shear walls and walls by loadcase” report
The “Worst case forces” column in the “Summary of code checks” table has been improved. As of version 2022.g, the worst case forces in the table include the minimum eccentricity and are amplified in order to take into account the second order effects caused by the slenderness of the column, in accordance with the code's criteria. - Improved ratio reports
The “Job ratios” and “Reinforcement ratios, per diameter” reports include the measurement of column starts with external fixity that do not start on a foundation element. - Improved calculation of the dimensioned length of beam spans in the "Frame editor"
In some cases where two continuous beams with different widths meet, the span lengths displayed could be slightly longer than the actual span lengths. - Reinforced and prestressed joist floor slabs
An error that prevented reinforced and prestressed joist floor slabs from being imported in jobs where the Spanish structural code "Código Estructural" standard was selected has been fixed. - Improved shear wall removal
After deleting a shear wall in "Column Definition" its associated beams do not remain on the floors where it was defined unless it was in contact with a panel. - Check fire resistance of the current group
An error that occurred in the "Fire check of the current group" option if shear walls were defined in the job has been fixed. - Improvement in the “Tags > Assign” option
The joints reference is drawn in the “Show References > Joints” option is checked. - “Column forces and reinforcement” report
An error that occurred when obtaining the “Column forces and reinforcement” report if only generic columns were installed in the job has been fixed. - Checking column forces
An error that occurred when checking column forces in jobs that had only defined the foundation level has been fixed. - Improved calculation of reinforcement ratios for punching shear checks
The calculation of reinforcement ratios “⍴x” and “⍴y” in punching shear checks has been improved. In some cases, the base reinforcement was not taken into account correctly. Furthermore, as of version 2022.g, the default reinforcement is taken into account. - Improved punching shear checks
In the drop panels of waffle slabs, the checks are carried out on the perimeter corresponding to the area outside the punching shear reinforcement as long as this perimeter is completely enclosed by the drop panel. - Improved punching shear checks
After adding reinforcements, the reinforcement ratios are updated if there are changes in the critical perimeter. - Column reinforcement drawings
An error that occurred during the generation of drawings when the transverse reinforcement of a generic section column was not correctly defined has been fixed. - Improved import of beams from BIM models
When importing a BIM model with grouped beams, only the first one was imported. Now, they are all imported. - Updating the BIM model
An error that occurred when updating a BIM project after adding a floor with beams in the project has been fixed. - Sharing the BIM model
An error that occurred when selecting the "Share" option from "BIMserver.center" in the top menu has been fixed. The error occurred when inverted type reinforced joist floor slabs with a central edge value equal to 0 were defined in the job.

Changing the user account when linking to a BIMserver.center project
As of version 2022.g, applications that can be linked to a project on the BIMserver.center platform allow the user account to be changed during the project selection process. To do this, a "Disconnect" button has been added below the user's name and image in the "Project selection" panel. When disconnecting the active account, the credentials of the account (email and password) that the user wishes to work with can be entered.

Implementing Spanish code "Código Estructural"
Spanish code "Código estructural" (Real Decreto 470/2021) has been implemented for analysing and designing rolled and built-up section steel structures in CYPECAD and CYPE 3D.
In the previous version (2022.c), it was already implemented in CYPECAD, CYPE 3D, Reinforced concrete cantilever walls, and Embedded retaining walls, for analysing and designing concrete structures; and in CYPE Connect Steel and StruBIM Steel for designing and checking steel connections.

Other improvements and corrections
Version 2022.f of CYPECAD includes other minor improvements and corrections of the program for certain cases:
- Foundation
An error that occurred when analysing jobs containing foundation elements with soil-structure interaction in floors affected by wind loads has been fixed. - Non-structural beams
Non-structural beams or limit beams are allowed at the ends of timber joists. - Columns schedule
An error that occurred when obtaining the columns schedule of jobs containing a code without U.L.S checks, and that had a special character in the job name (punctuation marks, for example) has been fixed. This error occurred in the changes made in version 2022.e. - Columns schedule
An error that occurred when obtaining the column schedule in some unique cases involving sloping roofs has been fixed. - Concrete code selection
There is an improvement in the organisation of concrete codes when it comes to selecting them. - Foundation beam dimensioning
The dimensioning of foundation beams in walls in the drawing of frames has been improved. In some cases, the length shown was somewhat longer than the actual length. - Jobs with shear walls and deleted temporary files
An error that occurred when a job with shear walls was opened and its temporary files were deleted after it had been analysed, has been fixed. - Sharing with BIMserver.center with the Spanish structural code "Código Estructural" as the selected standard
In the "Share" dialogue box (BIMserver.center menu > Share) users can select the "CYPE Memorias CTE" option if the selected standards are those corresponding to the Spanish structural code "Código Estructural".

Exporting concrete quantities to the BIM model
After carrying out the complete analysis of the job, the information of the concrete volumes can be exported to the BIM project. To do this, the "Quantities" option has been implemented in the "Share" dialogue box that appears when the "Share" option is clicked in the "BIMserver.center" menu.
The export of concrete quantities to the BIM model can be imported and interpreted by other tools such as Open BIM Quantities.
In Open BIM Quantities, this data can be used for carrying out the bill of quantities of the concrete used in the project.

Processors used for the portal frame generator
The portal frame generator makes extensive use of all the available processors. This can significantly slow down the performance of other programs that are installed on the device while the program is designing the frames. In order to avoid this, an option has been added (Project menu > General options) that allows users to establish the number of processors that the program will not use while it is designing the frames.

Exporting additional rebars of reinforced concrete beam frames to the BIM project
CYPECAD version 2022.f allows users to export additional rebars of reinforced concrete beam frames to the BIM project.
Therefore, the concrete elements that export their reinforcement to the BIM project up to this version are:
- Beam frames
- Columns
- Corbels
- Foundation elements
Footings, pile caps, strap beams and tie beams. - Floor slabs
Joist, waffle, hollow-core plate, composite, and flat floor slabs.
This reinforcement can be viewed, along with the reinforcement exported from StruBIM Shear Walls, in the StruBIM Rebar program.
They can also be viewed in the "Results" tab (Groups menu > 3D view with details).

Critical temperature
As of version 2022.f, CYPECAD and CYPE 3D allow the critical temperature of steel sections to be obtained for fire situations. The value of the temperature that each section must reach for collapse to occur is calculated by means of an iterative procedure, taking into account the combinations established by the code selected for the fire situation as well as the mechanical properties of the steel at elevated temperatures.
The results can be checked on screen, or in a summary table that includes the critical temperature and the shape factor corresponding to each of the structure's sections. This facilitates the use of catalogues of manufacturers of intumescent paint in order to obtain the thickness necessary to ensure that the load bearing capacity of the structure is maintained for the time required by the applicable fire code.
Since the critical temperature value of a section depends on the demand capacity ratio or demand factor of the section, this new feature is an excellent tool for optimising the total cost of the structure including its passive protection for the required fire resistance time.
