Bars defined as column-type structural elements
CYPE 3D is an agile and efficient program brought about to carry out structural calculations in three dimensions of bars made of concrete, steel, composite steel and concrete, aluminium, timber or any other material; shells (two-dimensional elements with a constant thickness whose perimeter is defined by a polygon). It includes the design of joints (welded and bolted rolled and welded steel I -sections and hollow sections) and of foundations (pad footings, pile caps and baseplates).
This webpage explains bars defined as column-type structural elements.

CYPE 3D allows users to introduce bars made of concrete, steel, composite steel and concrete, aluminium, timber or any other material.
The program designs the section and provides its optimum size for bars composed of steel, aluminium, timber or concrete (if they have been defined as column or beam-type structural elements).
Composite steel and concrete bars can be defined if they have been introduced as column-type structural elements and, even though they are not designed automatically, they are checked by the program with the properties that have been indicated by users.
As of the 2016.a version, users are required to define the structural function an element carries out in CYPE 3D. There are 4 different structural types available: Generic-type structural elements, Tie-type structural elements, Column-type structural elements and Beam-type structural elements.
This webpage describes bars defined as column-type structural elements. To consult the properties of bars defined as other types of structural elements, please consult the following links: Generic-type structural elements, Tie-type structural elements and Beam-type structural elements.
Levels and grids must be defined in CYPE 3D when bars defined as Column-type structural elements are introduced. A Column-type structural element can be assigned the following materials: Reinforced concrete (rectangular and circular concrete sections), Steel (rolled, welded or cold-formed) and composite steel and concrete sections.
Column-type structural elements are designed, edited and checked using the Advanced column editor for the design codes implemented in the editor. Usually derogated codes or codes no longer in use are not available for use with the editor.
Columns are composed of elements whose structural type has been defined as being a column. A column can be composed of one or more elements. The column elements making up the column are vertical and have the same level parameters. Columns can be created in 3 ways:
Regardless of how they are created, the program will manage the composition/decomposition of the previously introduced columns. It is recommended columns be created using option 3. The “New column option” allows users to create a column between a range of indicated levels with the reference and sections defined by users by clicking with the mouse button at the position where the column is to be introduced.
The element must be vertical and be defined as being between two different levels. The element must be divided into bars, however, in the case of concrete columns, the reinforcement will be continuous along its complete length.
Once a group of elements has been defined as being a single column, CYPE 3D ensures the level parameters are the same for all of them. The level parameters of the column are defined using the “Describe disposition” option in the “Bar” menu.
The remaining specific editing option for columns are located in the “Edit columns” option in the “Bar” menu. This option displays a toolbar containing the possible edit options. These options are:
The program generates a solid model of the column taking into account floor slab depths at the nodes of the elements it is composed of. CYPE 3D automatically analyses these floor slab depths based on the elements reaching the nodes to established the real size of the column as well as the free height of the spans it is composed of.
Included in the “Planes” menu are the Levels and Grids options. These options are essential when introducing, revising and viewing jobs with Column and Beam-type structural elements:
The basic version of CYPE 3D (without modules) designs three-dimensional node and bar structures with steel, concrete and generic material sections, and flat shells. Ties working only in tensions can be introduced. The program designs and checks steel sections. Users can upgrade this basic CYPE 3D version by adding any of the CYPE 3D modules to their user license.
CYPE 3D version limited to 50 nodes and 50 bars. No other modules can be added and the design and optimisation of sections is limited to structures containing no more than 10 nodes and 10 bars.
CYPE 3D has a series of modules available which can be acquired separately:
There are two reduced versions of CYPE 3D:
CYPE 3D limited to 2 dimensions: CYPE 3D version limited to a two dimensional analysis. The same optional modules are available as those for CYPE 3D.
CYPE 3D student version: CYPE 3D version limited to 50 nodes and 50 bars. It does not include section design or any of the CYPE 3D modules.
