CYPECAD

Minor improvements and corrections

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

  • An error that could occur in the "Punching shear - Summary of all the element checks" option if floor slabs were defined in the floor plan on several levels has been fixed.
  • An error that occurred during column design when there was no valid reinforcement diameter for a certain column due to the configuration of "Column reinforcement tables" has been fixed.
  • An error that could occur when importing BIM models depending on the concrete code selected by default has been fixed.
  • The warning concerning the impossibility of deleting a wall if another wall starts on top of it has been improved.
  • An error in the generation of cells of block walls that could occur when the thickness of the block walls is high has been solved.
  • An error that could occur in rare situations when checking the rotational stiffnesses of connections has been fixed.
  • An error in "Configure combinations for each limit state" in projects following the Spanish code "Código Estructural" has been fixed.
  • Certain error warnings in the beam frame design process have been improved. These warnings could be confusing if they arose in frames that had been rearranged.

Wind action justification report for Spanish building code "CTE DB SE-AE"

As of version 2022.d, CYPECAD can generate a wind action justification report for Spanish building code "CTE DB SE-AE".

Spanish structural code "Código Estructural"

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

Implemented in CYPECAD and CYPE 3D, for analysing and designing steel structures.

In the previous version (2022.c), this 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 analysing and checking steel connections.

Other improvements and corrections

CYPECAD version 2022.c includes other minor improvements and corrections of the program that may occur in rare situations:

  • As of version 2022.c, the buckling height of each span can be modified when editing concrete walls and shear walls.
  • The "Maximum value" and "Minimum value" of "Contour plots - Ground bearing pressures - By loadcase" can be selected.
  • An error that did not include columns starting on beams or mat foundations in groups above the foundation in the foundation load distribution has been fixed.
  • An error that occurred when exporting the project to the BIM model after assigning shear walls and not reanalysing the project has been fixed.
  • An error that occurred when entering a generic column that has three points with very close X or Y coordinates (< .0001 m) in its outline but which are not the same, has been fixed.
  • The "Job ratios" and "Reinforcement quantities, per diameter" reports have been improved. Now, the bottom reinforcement of composite slabs is included in its section. Previously, it was included in the "Joist slabs" section.
  • The "Form quantities report" has been improved. Now, the depth value of the form is displayed without being rounded.
  • An error that did not allow stairs with one of their ends on a column to be defined has been fixed.
  • An error in the 3D view and in the export to BIMserver.center that occurred in certain cases in jobs when there were beams defined under floor slabs has been fixed. This error occurs in version 2022.b due to changes made to optimise the 3D view and the export to BIMserver.center.
  • An error that occurred when viewing haunches in 3D and when exporting them to BIMserver.center has been fixed. This error occurs in version 2022.b due to changes made to optimise the 3D view and the export to BIMserver.center.
  • The export of the deformed shape to BIMserver.center has been improved. Sometimes, it was exported in a rotated position compared to the structure.
  • An error that occurred when obtaining the foundation layout plan has been fixed. This could occur when there are several walls with strip footings connected to others with pad footings in the foundation.

Compatibility of the seismic design requirements in the Dominican Republic and El Salvador with the ACI concrete design codes

As of version 2022.c, if concrete codes ACI 318M-14 or ACI 318M-19 are selected, the structure can be analysed and designed based on the requirements from Dominican Republic code R-001 2011 (Reglamento para el Análisis y Diseño Sísmico de estructuras) as well as those from El Salvador code NTDS 1997 (Norma Técnica para Diseño por Sismo).

Filtering columns

New option available in "Column definition > Introduction > Columns, shear walls and starts" that allows visible columns, shear walls and starts to be selected according to their initial and/or final group. It only affects the onscreen display of these elements, which can be useful in projects containing a large number of columns and shear walls, to use the tools from the new option on a reduced group of them.

Exporting reinforcement bars for concrete structural elements to the BIM model

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

  • Columns.
  • Corbels.
  • Foundation elements: footings, pile caps, and strap and tie beams.
  • Floor slabs: joist floor slabs, waffle slabs, hollow core plate floor slabs, composite slabs and flat slabs.

These reinforcements can be viewed, along with the rebars exported from StruBIM Shear Walls, in the StruBIM Rebar program.

Concrete wall continuous reinforcement in intermediate floors

Option available when editing concrete walls, allowing the definition of which floors the reinforcement of the walls should not be cut.

This option is very useful, for example, in jobs with suspended floors or when intermediate floors must be generated in order to define a ramp.

Selecting sections of the beams when importing the BIM model

In version 2022.c, importing beams from the BIM model has been improved for selecting different types of materials and sections.

In the "Beam" stage of the BIM model import assistant, a list with the detected beams is displayed. In the "Cross-section" column, the assigned cross-section is indicated. By clicking on each cell, the beam section selection panel can be accessed.

The program automatically assigns the rectangular and circular concrete sections. For each one of the remaining sections, the corresponding CYPECAD section must be assigned. The assignment is automatically saved for subsequent imports.

Implementing Spanish code "Código Estructural"

Spanish code "Código Estructural (Real Decreto 470/2021)" has been implemented for analysing and designing concrete structures in CYPECAD, CYPE 3D, Reinforced concrete cantilever walls and Embedded retaining walls.

Other improvements and corrections

CYPECAD version 2022.b includes other minor improvements and corrections of the program that may occur in rare situations:

  • The process for importing beams from a BIM project has been improved, in order to correctly detect the sections of the beams exported from programs such as ArchiCAD. We continue working to make this functionality similar to that of the columns.
  • Errors such as: "Expression: desplRotulos->portico[p].numTramos > 0" that could occur after carrying out a number of operations (joining, dividing, etc.) in beam frames have been fixed.
  • An error that could occur when adding loads to "Situation 2" of wall soil pressures has been fixed.

 

Direct link to CYPECAD from CYPE Architecture

A direct connection with CYPECAD has been added to the BIMserver.center section of the CYPE Architecture program. When using this feature, CYPE Architecture automatically exports the project to BIMserver.center and directly opens the program and the project in CYPECAD, speeding up the connection between the two programs considerably.
