CYPECAD

CYPECAD version 2024.d includes the following improvements and corrections to the program for some specific cases:

• Pre-stressed ceramic slabs for floor slabs manufactured by Cerámica Pastrana, S.A. have been added. By incorporating the technical data sheets of these products in the program, they are now available for use in the "Selection of hollow core plates".
  
  
• The design of portal frames has been modified to consider paragraph 5.6.3(3) of Annex 20 of the Spanish structural code "Código Estructural" as well as Eurocode 2, Part 2-2. In order to meet the criteria indicated in these sections, in the case of fire resistance equal to or greater than R90, an extension of the negative reinforcement is applied up to 0.3 times the span length.
  
  
• The updating of DXF/DWG templates by pressing the F5 key has been improved. In the previous patch, there was a new implementation for updating the templates, if new layers appeared, these were automatically made visible. This was made for updating via 'Edit templates > Import templates - Update file'. The same now applies when pressing the F5 key on the main screen.
  
  
• The “Diagrams of pressures acting on the wall > Pressure diagrams list” has been improved. Previously, when adding a "Generic pressure diagram" after having entered another one without accepting the panel, the data of the first one was lost.
  
  
• An error that could occur in the "Recover reinforcement copy of all groups" option has been solved. This occurred when the angle of the longitudinal reinforcement of a slab was greater than 180º. Now, when an angle greater than 180º is entered, in a flat slab or a waffle slab, it is automatically modified.
  
  
• The entry of grid lines has been improved. Templates defined in "Column definition" can now be snapped.
  
  
• An error that could occur in some situations when displaying the 3D view of concrete walls with continuous reinforcement on some floors has been fixed.
  
  
• The 3D view of the reinforcement of circular frames, or frames where the origin coincides with the end, has been improved. Due to a programming error, in these cases, every time "3D view with details" was launched, the order of the beams in these frames was inverted and the reinforcement was shown alternately, correctly positioned and incorrectly positioned.
  
  
• The "Electrowelded meshes > Check" has been improved. The checking process has been optimised to reduce processing time. More optimisations of this kind will be carried out in future versions.
  
  
• The entry of generic column sections has been improved. The ability to enter points by snapping the elements of a template, which was lost in version 2024.c, has now been restored.
  
  
• An error that could occur very rarely during the analysis process when a wall was in contact with flat slabs and the direction of this wall was not parallel to the direction of the reinforcement of one of the slabs involved, has been solved.
  
  
• The ratio analysis for primary beams according to Eurocode 8 requirements 5.4.3.1.2(5)P and 5.5.3.1.3(5)P has been improved.
  
  
• An error has been corrected in the units shown for air density in the wind action report according to Eurocode 1-4.
  
  
• The steels and bar diameters commonly used in Thailand for the ACI 318M-11 (USA) concrete standard have been incorporated.

As of version 2024.d, CYPECAD has implemented the reading of the fixed points of columns included in the IFCs generated by REVIT. For this reading to be carried out correctly, REVIT must use column families created with a fixed point which is the origin of the coordinates of this IFC.

More information on how to create or use these families can be found at https://learning.cype.com/en/faq/how-can-the-fixed-points-of-revit-columns-be-read/. In the same link, users can also download the parameterised column families supplied by CYPE for different Revit versions.
