Update history​​

CYPECAD

In the 2018.a version, a new type of material has been implemented for it to be assigned to columns. It is a generic material whose properties are defined by users. These columns can have a rectangular, circular, or generic section, or a section determined by the mechanical properties introduced by users. Generic material columns intervene in the force analysis of the structure. Their forces and deformed shape can be consulted, although their sections are not checked.

Definition of the material

Users can create a generic materials library to assign to different columns. The generic material will be defined by the modulus of elasticity, Poisson’s ratio and the specific weight.

The mechanical properties of rectangular, circular or generic columns can be established by users or calculated by the program.

Generic sections

A section editor has been implemented in the program which allows users to define the geometry of the section. The sections are stored in a library which also contains generic concrete section column.

In the section editor, users can create a section by defining the points of its external perimeter and openings, if any. The outline of a previously introduced section can be edited by adding, moving or deleting

Sections defined using an equivalent rectangle

For this type of section, the dimensions are defined of the equivalent rectangle that would encompass the real section and its mechanical properties.

The 2018.a version includes this new CYPECAD module, which has been developed to:

  • Calculate the forces of generic material columns, which are defined by providing their modulus of elasticity, Poisson’s ratio and specific weight.

  • Calculate the forces of generic reinforced concrete sections and check their longitudinal reinforcement.

More information on the properties of this CYPECAD module can be found in the sections on Generic material columns and Concrete columns with generic sections of this webpage.

As of the 2017.j version, users can create different types of concrete with user-defined properties.

The concrete library can be accessed from the “General data” dialogue box (Project > General data). The different types of concrete of the library, as well as those established by the code, can be assigned to reinforced concrete elements.

The “Base shear condition verification” has been implemented in the “Modal spectral analysis” of the “General seismic design method”. This check is optional and is implemented in the same way as, of previous versions, for the standards that contemplate this verification.

The section: “Estimation of the fundamental period of the structure” has been added, where users can indicate its approximate value in the “X” and “Y” directions. This data is used in the base shear verification.

The “Base shear condition verification” section has been added to the bottom panel, where users can select three options:

  • Do not carry out the static base shear correction
  • Specify the static base shear percentage
  • Specify the modification factors

All the sections contain help buttons which provide information on the different options.

In general, the “Spectral modal analysis” data panel of the seismic analysis “General method” has been reorganised, the “Eccentricity factor” field has been added and the “Ductility” data can now be introduced for the “X” and “Y” directions.

Norma Brasileira ABNT NBR 6118 (2014). Projeto de estruturas de concreto – Procedimento.

Implemented in Embedded retaining walls and Reinforced concrete cantilever walls. This code was already implemented in CYPECAD, CYPE 3D and other CYPE programs.

The 3D view of the building has been renovated. As of the 2017.i version, the information of the 3D view displayed in CYPECAD is organised in layers. There are two groups; Projects and Elements, which display the information in different ways:

  • Project group
    This group contains the elements of the project organised by floor and the information of the integrated 3D structures, if present. Users can activate or deactivate floors (using the “bulb” icon), or alternatively, using the “cube” icon, choose a wire or solid view.



  • Elements group
    This group contains the parts of the structure organised by type and subtype (walls, beams, floor slabs - timber joist floor slabs...). This way, users can act on the same type of elements of the complete project. The viewing options are the as those for the Project group.


If the job in CYPECAD is connected to a BIM model, users can select two types of 3D views from the “Beam Definition” and “Results” tabs: “3D view of the building” and “3D view of the building, including the BIM model”. For this last type, the Elements group includes a BIM model section:

  • BIM model section of the Elements group
    In this section, the structural model and its interaction with the architectural model can be viewed. This allows users to configure the view of the elements included in the BIM model independently from those of the structure. For example, the columns defined in the BIM model are activated or deactivated independently from those introduced in CYPECAD.

Several column design and check processes have been improved to optimise analysis times. In some cases, such as for projects where seismic loads have been applied, the time required to analyse the project has been reduced significantly.

As of the 2017.i version, CYPECAD and CYPE 3D allow users to work on several projects simultaneously.

Once a project has been opened in CYPECAD or CYPE 3D, users can access the general program menu to open another file of these programs and work on it or on both projects at the same time.

This allows users to, for example, edit the results of a structure that has already been analysed or introduce a new structure whilst another is being analysed. It is even possible to analyse several projects at the same time. The number of executions is not limited.

There is one limitation, it is not possible to keep the same file open more than once.

Código Reglamentario para el municipio de Puebla (2003). Implemented in CYPECAD and CYPE 3D.

When applying Brazilian design codes, the diameter of circular columns is indicated with the Greek letter “Ø” instead of the word “diameter”.

A button has been added in the top part of the column reinforcement editor which allows users to design column stirrups when the longitudinal reinforcement has been modified manually.

Options have been added to copy post-tensioned elements. These have been included in the “Copy elements of the group”, “Copy symmetrical elements” and “Copy elements in another group” dialogue boxes.
