Update history​​

CYPECAD

Norma Chilena Oficial Diseño Sísmico de Edificions (Includes modifications of decree n° 61 (V. and U.) of 2011).

This code was already implemented in previous CYPECAD and CYPE 3D versions. Now, with the 2015.e version, a user seismic spectrum can be defined. A design spectrum must be defined to carry out the seismic analysis of the structure. Each seismic resistance code provides the criteria that are to be followed within a specific territory for the seismic action to be considered in the project. Nonetheless, the project designer can adopt, under his/her responsibility, different criteria to that established in the code. The program offers different ways to proceed for the use of either way. The design seismic spectrum can be:

  • Calculated in accordance with that specified in the seismic code to be applied.
  • Specified by users based on his/her criteria.

Diseño estructural. Cargas de viento.

Implemented in CYPECAD.

  • BAEL-91 (R-99) (France)
    Fascicule n°62 – Titre I- Section I Règles techniques de conception et de calcul des ouvrages et des constructions en béton armé suivant la méthode des états limites – BAEL 91 révisé 99.
  • NTCRC:2004 (Mexico)
    Normas técnicas complementarias del reglamento de construcciones para el Distrito Federal

These codes were already implemented in CYPECAD, CYPE 3D and other CYPE programs as of previous versions. Now, in the 2015.e version, these codes are implemented in “Punching shear verification” and hence, also in the punching shear check carried out by CYPECAD in accordance with code criteria. This check was implemented in CYPECAD in the 2015.a version and, since then, coexists with the tangential stress check.

Complete and trim punching shear perimeter

Two options have been implemented which allow users to modify the punching shear perimeter calculated by the program (Results > Flat/Waffle slabs > Punching shear):

  • Complete perimeter

    Allows users to draw the punching shear perimeter on zones at which it has been trimmed by the analysis or manually.
  • Trim perimeter

    Allows users to trim the punching shear perimeter of a column.

Users can use the “Regenerate perimeters” option (Results > Flat/Waffle slabs > Punching shear) to eliminate any modifications carried out on the punching shear perimeters.

Punching shear check at supports with adjacent dropped beams

The option “Supports to which dropped beams reach” has been implemented (Job > General data > By position button > Slab options > Punching shear) which does not allow the punching shear check to take place at a support if the ratio between the depth of the dropped beams adjacent to the support and the depth of the slab is greater than the value defined in this option. The default value for this ratio is 1.20.

Improvements of the codes indicated below have been implemented or included in the application. Detailed information can be found in the previous sections:

  • Concrete code

  • Fire safety. Fire resistance of the structure
    • ABNT NBR 15200:2012 (Brazil)

Projeto de estruturas de concreto en situação de incêndio.

Implemented in the “Fire resistance check” module and checks the fire resistance and designs the protective coatings for beams, floor slabs, columns, concrete shear walls and walls using the tabular method defined in this code.

With this code, the “Fire resistance check” module carries out the following checks and designs:

  • For the indicated structural elements for which a protective coating can be defined, the program designs the minimum thickness of the protective coating so that the requirements of the applied code are met.
  • For the indicated structural elements for which a protective coating can be defined, the program checks the element with the assigned fire resistance data.
  • If a coating is assigned to a structural element and the program verifies it is not needed to meet the requirements stated in the corresponding code, the program will indicate the coating of the structural element is not necessary, and so the minimum thickness of the coating will be applied for construction reasons.

Users must have the “Fire resistance check” module to be able to carry out these checks, as well as the corresponding aforementioned structural elements.

The fire resistance check in CYPECAD is activated in the “General data” dialogue box (Job > General data). Upon activating it, a dialogue box opens where users can define the required resistance, the compartmentation of the floors (with or without compartmentation) and the coatings of the construction elements. If users wish to use the “ABNT NBR 15200:2012” fire resistance code, the “ABNT NBR 6118:2014” or “ABNT NBR 6118:2007” concrete code must be selected in CYPECAD.

The corresponding Brazilian code required to carry out the fire resistance checks of steel beams and columns in CYPECAD and steel sections in CYPE 3D will be implemented in upcoming versions.

Normas Técnicas Complementarias para Diseño por Sismo para Guadalajara 1997.

Implemented in CYPECAD and CYPE 3D.

Código Hondureño de la Construcción. Normas Técnicas. Capítulo 1. Cargas y fuerzas estructurales. Diseño por Sismo

This code was already implemented in CYPECAD and CYPE 3D in previous versions. Now, with the 2015.d version, the new seismic map (which displays zones 3, 4 and 5) has been implemented and values between 0.10 and 0.60 can be introduced for the “Factor de zona sísmica” (Seismic zone factor).

Reglamento INPRES - CIRSOC 103 - Parte I - 2013. Normas Argentinas para Construcción Sismorresistente.

Implemented in CYPECAD and CYPE 3D.

  • CIRSOC 201-2005 (Argentina)
    Reglamento Argentino de Estructuras de Hormigón CIRSOC 201 (Julio 2005).
  • IS 456: 2000 (India)
    Indian Standard. Plain and reinforced concrete code of practice (Fourth Revision).

These codes were already implemented in CYPECADCYPE 3D and other CYPE programs as of previous versions. Now, with the 2015.d version, the codes are implemented in “Punching shear verification” and therefore in the punching shear checks carried out by CYPECAD, in accordance with code criteria. This check was implemented in CYPECAD in the 2015.a version and, since then, coexists with the tangential stress check. 

Some corrections have been carried out on the deflection limits that are applied for the Brazilian concrete code "ABNT NBR 6118:Projeto Junho 2013".

The specific export to IFC format (Industry Foundation Classes) for the 2015 version of Revit® Architecture has been implemented in CYPECAD and CYPECAD MEP. Therefore, as of the 2015.b version, users can choose amongst the following export formats:

  • IFC 2x3
    Generic format
  • IFC4
    Generic format
  • IFC 2x3 for Revit (2012, 2013, 2014 and 2015 versions)
    Specific format for Revit®. There are four options when exporting to Revit®. The option that is selected will depend on the Revit® version which it is being exported to: 2012, 2013, 2014 and 2015.
  • IFC 2x3 for Archicad
    Specific format for Archicad®
  • IFC 2x3 Allplan (2014 version and earlier versions)
    Specific format for Allplan®. There are two export options for Allplan®, one for the 2014 version and another for earlier versions.
