Implemented in CYPECAD and CYPE 3D.
Before version 2022.a, all CYPE programs shared the same settings for contour plots and the background colour of the screen. As of version 2022.a, the settings for each program are different.
CYPECAD version 2022.a also includes other minor improvements and corrections of the program that could occur in rare situations:
- Isolated footing reinforcement checks
As of version 2022.a, isolated footing reinforcement checks will be carried out considering the number of actually placed bars. Previously, they were carried out with distributed reinforcement that could lead to certain inaccuracies, especially in the case of smaller footings.
- Warnings during the analysis process
- In the analysis process, certain warnings can be repeated throughout the analyses carried out in the same job. As of version 2022.a, users can choose not to see these warnings again.
- Warnings such as "Diagonal bracing data has been modified. Re-analyse the job in order for this to be considered during the design" that appeared in previous versions each time a diagonal brace or sloped beam was analysed, are now only displayed with the first beam or diagonal brace that is modified.
- The "Colours for representing contour plots" button has been added to contour plots.
- The size of gltf files exported from CYPECAD has been reduced so that display in BIMserver.center is smoother.
- Two buttons have been added for accessing the standard configuration of strap and tie beams in the "Strap and tie beams" menu.
- The "Soil-structure interaction" option can be activated in the "Show References" option to show the subgrade modulus for footing and the axial stiffness of pile caps. This can be useful when assigning values in the "Soil-structure interaction" option.
- The drawing of texts and foundation elements has been improved in the "Soil-structure interaction" option. Previously, the texts were not displayed clearly depending on the background colour.
- Variable depth beams are correctly exported to IFC files. Previously, they were exported as constant depth beams.
- Messages such as "The first floor of column P1a is the same as the last floor of the column on which it starts" have been removed for columns starting on other columns.
- An error that occurred when adding floors to a job with shear walls whose reinforcement was blocked has been fixed.
- An error that occurred when the seismic analysis was carried out with code ASCE 7-16 in cases where the ductility or the displacements factor is less than 1 has been fixed.
When entering post-tensioned tendons, users are allowed to do so in any direction, although the preferred directions are those corresponding to the reinforcement of the floor slab. While the introduction is being carried out, a blue line is displayed if the direction matches those of the reinforcement of the floor slab and green in all other cases.
The frame design process has been modified in order to make better use of the available processors.
It is difficult to quantify the achieved improvement, however, the example below shows a comparison of the frame design times of various jobs. All calculations have been carried out on a computer with an "Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz, 3696 Mhz, containing 6 main processors and 12 logical processors".
| Job | Total surface | Time in previous versions | Time in current version | Improvement |
| 6-storey building | 650 m2 | 1' | 21" | 65% |
| ESC-RETICULAR (Example job) | 1440 m2 | 2' 26" | 1' 38" | 33% |
| 10 storey building | 2619 m2 | 4' 14" | 1' 31" | 64% |
| 19 storey building | 12208 m2 | 51' 19" | 26' 31" | 48% |
| 20 storey building | 46746 m2 | 1h 5' 18" | 36' 58" | 43% |
| 42 storey building | 61621 m2 | 4h 50' 54" | 2h 17' 51" | 53% |
From version 2022.a, embedded beams and crown beams can be defined individually in the editing panel of the different wall types as well as having a general definition.
As of version 2022.a, beams can now be entered in a BIM project when they have a correct parametric definition in the IFC file (section + extrusion or section + faces). Users can import beams from our CYPE Architecture modeller, as well as from other BIM modellers.
CYPECAD version 2021.g includes some minor improvements and corrections for the program that could occur in rare situations:
- Exporting plans to PDF format has been improved. Several problems with the "Adobe PDF" printer emulator have been solved.
- As of version 2021.g, beam reinforcement tables defined for standard ACI 318M-14 in jobs following standard ACI 318M-19 can be imported.
- As of version 2021.g, users can snap templates generated during project creation using the "Automatic Introduction IFC" option.
- An error in the discretisation of slabs with sloped planes which could occur due to an accuracy problem when several coplanar panels come into contact has been fixed.
- An error that occurred when activating snaps after adding a floor into a project imported from a BIM model has been fixed.
- Snapping beam axes in the beam input process when the "Orthogonal on/off" option is activated has been improved. Due to a previous improvement in this option, this snap was only possible if the mouse cursor was placed exactly on the beam axis.
Version 2021.g of CYPE’s programs is a closing version of the 2021 version.
As well as the new features and improvements expressly indicated in each version of CYPE software, process optimisation involving internal updates for all our programs is normally included. In each revision, all programs are systematically checked and changes are made to improve their performance, therefore, we recommend that our users (in this case those of v.2021) always update their version to the latest one, regardless of the country for which they are using CYPE software or the language in which it is installed.
CYPECAD version 2021.f also features other slight improvements and corrections to the program that may occur in specific situations:
- Improvement in the "For some reinforcement the compliance factor is less than 100%" warning. Walls with a compliance factor lower than the one selected by the user, and walls with a compliance factor lower than 100% are now reported separately.
- In the "Soil-structure interaction" and "Punching" options, the column references are shown if they are active.
- In the "Soil-structure interaction" section in "Job data report", more information has been added to the strip footings of walls.
- Performance has been improved for several options belonging to property assigning types of menus, such as "Beams - Rigid diaphragm in unconnected beams", "Punching - Lock/Unlock perimeter". When selecting this type of option, the elements are shown in different colours depending on whether or not their properties have to be assigned. Previously, these were displayed after selecting the properties to be assigned.
- The "Panel report" section in the "Job data report" has been improved. Now, the name of the panel is displayed instead of the coordinates.
- An error that arose when analysing jobs that generated result files larger than 2 gigabytes has been fixed.
- Exporting "Hollow core slabs" to "Bills of quantities" has been improved.
- Users can consult the analytical model and the deformed shape of jobs copied to another computer.
- In the "Starts of columns, shear walls and walls by loadcase" section in the "Column, shear wall and wall forces and reinforcement" report, the "Starts" forces are displayed after calculating the structure without generating the reinforcement.
- The text for the "Timber" button in "General data" has been improved so that it is not oversized.
- The display of building elements in 3D view has been improved.
- The text in the initial floor of columns in the "Detailing of columns" drawing has been corrected. This text is shown if "Column detailing along all its height" is selected in the "Type of detailing" option.
- Detecting a column’s fixed point when importing jobs from BIM models or IFC files has been improved.
- Exporting timber element material to IFC files has been improved. Previously, it was exported as "Generic" material.
- Information on foundation elements has been improved in reports and the on-screen query.
- In the "BIMserver.center > Export" option, the data selected in "Deformed shape" is saved for future exports.
- In the foundation element editor, checks are no longer displayed after designing. They can be consulted by clicking on the "Check " button.
- An error has been fixed in the "Load report" section of "Job data report", which could appear if there are poorly defined construction elements on the job site.
- An error that occurred when inserting a strap beam connected to the end of a wall with the same direction has been fixed.
- Entering beams with the "Orthogonal on/off" option activated has been improved. If the second point inserted was close to the axis of a wall, that option may not have been applied.
- The texts for the titles of foundation element checks have been improved. Some checks with certain standards contained strange characters.
- "Additional information" has been restored to the footing check report. In the previous version, this was lost when the report's images were changed.
- An error in the design process for beams with variable depth has been corrected. This occurred in some cases in which the upper plane of the beam was inclined and one of its ends was a secondary beam.
- An error has been fixed in the "3D building view" for certain types of sections in joist floor slabs.
- An error that occurred when retrieving the "Pillar frame" plan has been fixed, this sometimes occurred after deleting stirrups in the column reinforcement editor.
- Distributing stirrups in frames of a single span in overhang has been improved. If one end was a secondary beam, they were always placed up to the external surface of this secondary beam, regardless of the selection made in "Beam Options" > "Reinforcement Arrangement" > "Stirrup Selection" > "Supports on beams".
- An error that occurred with regulation BAEL-91 (R-99) (France) in a job with a "Project situations introduced by the user" selection in "Limit states (combinations)" > "Ground bearing pressures" has been fixed.
- An error in the foundation element editor that occurred after changing the depth, resulting in the equilibrium check not being verified, has been fixed.
- An error in the punching check, that occurred very occasionally when the angle of the column and the panel had almost the same angle, has been fixed. Due to an accuracy error in the processor, it was determined as unequal in this situation.
- An error in the beam frame design process has been fixed in cases where a frame was blocked and, due to a force change, the overhang was modified at one end of the frame.
- An error that arose when entering jobs containing an integrated 3D structure that was not correctly defined has been fixed. From this version onwards, when this happens, a "You must check integrated structure, etc." type of message will be displayed. Normally, this type of error is automatically corrected when editing integrated 3D structures.
- An error in jobs combining both the concrete standard ACI 318-14 and the Ecuadorian NEC-SE-DS 2014 seismic action standard has been solved. From version 2021.f onwards, if the "Criteria of reinforcement by ductility" selection is "None", no criteria according to NEC-SE-DS 2014 will be applied, but seismic requirements according to a D, E, F category for ACI 318-14 will be applied.
