Bars defined as beam-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 beam-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 beam-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 Column-type structural elements.
Levels and grids must be defined in CYPE 3D when bars defined as Beam-type structural elements are introduced. A Beam-type structural element can be assigned the following materials: Reinforced concrete (rectangular, L-section, T-section..., lattice or prestressed beams) or steel (rolled, welded or cold-formed).
Beam-type structural elements are designed, edited and checked using the Advanced beam 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.
A beam is an element which has been assigned as being a beam-type structural element. A beam cannot be vertical, and the angle between its XZ plane and the vertical plane containing it must be zero (i.e. it must not rotate about the longitudinal axis of the beam). Beams can be grouped and so form continuous beams (beam alignments), with the following conditions:
Beams (and continuous beams) can be created in 3 ways:
In all these cases, the program will manage the composition/decomposition of beams that were introduced previously. The recommended option is option 3. The “New beam” option allows users to easily create a continuous beam by introducing the bars it consists of. To finish off the introduction, click on the right mouse button and at that moment, CYPE 3D will create a continuous beam with all the elements that have been introduced, if possible.
The element cannot be vertical, it does not have to belong to a level, however when they have been defined, they will be assigned to the closest level below the beam. The element can be divided into bars, but if it is a concrete beam, the reinforcement will be continuous along its complete length.
If the continuous beam is composed of more than one element, the deflection groups of the elements must be completely contained within the continuous beam. CYPE 3D will carry out the deflection analysis indicated by the design code for the beams of the continuous beam. No additional deflection limits have to be defined using the “Limiting deflection” option, even though in this case, the program will additionally carry out the check.
The remaining specific options for editing beams are found in the “Edit beams” option of the “Bar” menu. This option displays a toolbar containing options to edit beams. These are:
The beam reinforcement editing process implies that a solid model of the beam has been generated bearing in mind the size of the nodes of the elements making it up. CYPE 3D automatically obtains the geometry of these nodes based on the geometry and position of the elements not belonging to the beam. In any case if the analysis were not to be satisfactory, users can define their own node geometry.
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.
