New modules and programs


CYPETHERM ISO 10211 is an application conceived to determine the thermal transmittance of linear thermal bridges by solving and processing a finite element heat transfer analysis model, based on the UNE-EN ISO 10211 code. This application is located in the Building services group of the main CYPE program menu.

This program is part of an investigation to develop a software tool to integrate the numerical analysis of thermal bridges in the energy demand calculation of buildings, which is financed by the “Centro para el Desarrollo Tecnológico Industrial (CDTI)”, co-financed by the “European Regional Development Fund (ERDF)” and carried out in collaboration with the “Grupo de Ingeniería Energética” of the “Departamento de Sistemas Industriales” of Miguel Hernandez University in Elche (Alicante).


The main features of CYPETHERM ISO 10211 include:

  • Analysis in accordance with EN ISO 10211
  • Different thermal bridge models
  • Libraries or material catalogues
  • Analysis results

For users to be able to work with CYPETHERM ISO 10211, their user licence must include the “Numerical analysis of linear thermal bridges” permit.

Code implementation and improvements in its application

Concrete code

CIRSOC 201 2005 (Argentina) and IS 456: 20000 (India)

  • 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 CYPECAD, CYPE 3D and other CYPE programs as of previous versions. Now, with the 2015.d version, the codes are implemented in “Punching shear verification” More info link 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. More info link

Code regarding loads on structures. Seismic loads

CIRSOC 103-2013 (Argentina)

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

Implemented in CYPECAD and CYPE 3D.

CHOC-08 (Honduras)

Código Hondureño de la Construcción. Normas Técnicas. Capítulo 1. Cargas 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).

CHOC-08 (Honduras)

NTC 1997 (Mexico – Guadalajara)

Normas Técnicas Complementarias para Diseño por Sismo para Guadalajara 1997.

Implemented in CYPECAD and CYPE 3D.

Fire safety. Fire resistance of the structure

ABNT NBR 15200:2012 (Brazil)

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.

Punching shear verification

Complete and trim punching shear perimeter

Punching shear verification

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.

Punching shear verification



Shells in CYPE 3D


The 2015.d version of CYPE 3D allows users to define shells. Shells are flat two-dimensional elements with constant thickness and without openings, whose perimeter is defined by a polygon.


Shells are introduced in the global stiffness matrix of the structure using a three-dimensional finite element model composed of six-node (quadratic) triangular flat shells. The type of element used is based on the overlap of two locally decoupled elements: one provides the axial stiffness (membrane forces) and the other the bending stiffness (panel forces).






The following properties can be defined for each shell:

  • Thickness and subgrade modulus
    In the local Z axis direction
  • Material
    Concrete, rolled steel, cold-formed steel, aluminium and generic material (by specifying the modulus of elasticity and Poisson coefficient).
  • Position
    With respect to the introduction plane
  • Discretisation
    The density of the mesh can be controlled by defining the maximum size of the triangle in the local x and y axes.
  • Direction of the axes
  • Internal fixity
    Internal fixity between the edges and other elements of the structure.
  • External fixity
    It is also possible to define the external fixity of the edges, but in this case, the fixity is applied to all the shells sharing that edge. The possible external fixity configurations are the same as those available for the nodes of CYPE 3D.
  • Integration strips
    Integration strips in shells define lines on which, for a given strip width, the forces corresponding to the shell are integrated to obtain the bar forces.


The program contains an option which users can use to view the shells in 3D. They can be viewed filled in or simply their outline can be displayed. This can be indicated in the drawing preferences option in the Job menu.


To be able to use shells in CYPE 3D, users must have the permits required to use CYPE 3D.

Below are some examples of structures created with shells in CYPE 3D:








Retaining walls and cantilever walls

Increase loads at a specific elevation

As of previous versions, users could introduce loads along the top of the wall (horizontal -Q-, vertical -N- and moment -M). Now as of the 2015.d version, these load increments can also be specified at a specific elevation of the wall. The loads can be introduced at any phase and the program automatically and simultaneously takes them into account in all the following phases. In the case of Cantilever walls, the load can be defined as a permanent or live load, as occurs with the loads applied along the top of the wall.

Retaining wallsCantilever walls

Cantilever walls and Box culverts

Deactivate SETRA criteria for the French BAEL-91 code

When jobs are analysed in Cantilever walls and Box culverts in accordance with the French BAEL-91 code, the SETRA criteria (critère du SETRA “Les ouvrages de soutènement: Guide de conception générale”) can be deactivated.

Punching shear verification

Code implementation

As indicated in the previous sections, the “CIRSOC 201 2005” code (Argentina) and “IS 456: 2000” code (India) have been implemented in “Punching shear verification” and CYPECAD (for punching shear check in accordance with code criteria). More info link


Thermal study for Italy

Calculation of the climate data for cities

As of the 2015.d version, the program allows for the climate data analysis to be carried out for any location, in accordance with the requirements established by the UNI 10349 and D.P.R. 412/93 codes. The analyses are carried out by choosing the 2 closest province capitals, whose climate data is going to be used to obtain the irradiation values on the horizontal surface depending on the orientation and average monthly external temperature. Users define: the climate region, the climate zone, degrees, altitude and latitude.

Energy consumption limit report for buildings

Implemented in the “Studio termico” tab of CYPECAD MEP, is the option to generate the “Relazione tecnica di rispondenza alle prescizioni in material del contenimento del consume energetic degli edifice” report, in accordance with art. 28 of the “legge 10/91”.

Thermal study for Spain. CTE HE 1 and CTE HE 0

Integration of the results of other analyses when calculating the energy demand and consumption in accordance with CTE HE 1 and HE 0

The 2015.d version provides users with the explicit control of the values for ventilation, lighting and energy contribution for AC5 using solar thermal energy, which are values that are necessary in the HE 1 analyses for dwellings, HE 1 analyses for other uses, and HE 0 analyses for dwellings respectively.

In previous versions, the results for the ventilation, if present, were taken automatically, whilst the results regarding the solar thermal energy and lighting of the other tabs were not taken into account in the HE 1 and HE 0 analyses.

As of the 2015.d version, with the HE 1 and HE 0 “General data”, users can choose to use the values obtained in the other tabs of CYPECAD MEP (“Sanitation” (HS 3), “Solar thermal” and “Lighting”), manually state the values, or use the default values.

Improvements in the HE 1 and HE 0 justification reports

The HE 1 and HE 0 justification reports have been updated in the 2015.d version, generally improving and making the formats of all the tables included more uniform, as well as adding keys to these tables. This improvement affects both CYPECAD MEP and CYPETHERM HE.

Thermal study for France

Improvements and updates have been implemented in the Thermique tab of CYPECAD MEP for France related with the RT 2005, RT Existant and RT 2012 codes.

New features common to RT 2012, RT 2005 and RT Existant

As of the 2015.d version, the detailed catalogue of the French code: “Règles Th-U Fasicule 5: Ponts thermiques” has been implemented. Users can use this catalogue to import the linear thermal transmittance value of the selected thermal bridge (by defining the thermal bridges manually), and choosing it amongst those defined in the catalogue.

New features of the RT Existant

As of the 2015.d version, the thermal study corresponding to the RT Existant “par element” can be obtained in which the minimum properties of the construction elements can be checked.


Change of program name


As of the 2015.d version, the program is called CYPETHERM ASHRAE LOADS, becoming a part of the CYPETHERM program group of CYPE.



Availability in other languages

In the 2015.b version, the program, CYPETHERM LOADS was implemented. This application was conceived to analyse the thermal loads of buildings in accordance with the Radiant Time Series Method (RTSM) proposed by ASHRAE.

The first version of CYPETHERM LOADS was only available in Spanish and in English. Now, with the 2015.d version, the program is also available in Catalan, French, Italian and Portuguese. Furthermore, the name of the program has changed to CYPETHERM ASHRAE LOADS for all languages.



Report configuration

The 2015.d version of the program includes a helpful tool to configure the results report, which allows, amongst other things, to include the different sections that are available as well as select the type of load of each precinct to be included, even the specific moment for the cooling thermal loads.





Report improvements

The reports have been improved and different graphs have been included to offer a global view of the results.





Gas supply in English

The program “Gas Supply” is installed when the software is installed in English. This program can be found in the Building services menu. This program was already available in Catalan, Spanish for Spain, Spanish for Argentina and Spanish for Mexico.

Gas supply is a program created to analyse, design, size and check network, branched and mixed gas networks.
