The user should take into account that for two or more nodes to have the same displacements, an element or construction arrangement should be present in the structure which will be able to materialise this displacement equality. Ties cannot be assigned to nodes making up the edges of braced rectangles when the tied displacement has its projection on the plane of the braced rectangle. 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. The program designs the bars automatically if they have been defined as made of rolled, welded or cold-formed steel; aluminium or timber.
If they have been defined as reinforced concrete bars or bars made of a user-defined generic material, the program calculates the forces to which they are exposed and displays the results for each simple loadcase, combination or envelope; but their sections are neither checked nor designed. More information on these structural elements can be found on the Bars defined as generic-type structural elements webpage.

More information on this module, available for use with CYPE 3D and CYPECAD, can be found on the Concrete beams webpage. More information on these structural elements can be found on the Bars defined as beam-type structural elements webpage. CYPE 3D allows the user to introduce the ß buckling coefficients or the buckling length, the moment coefficient or the C1 coefficient of the lateral buckling critical moment formulation (if the selected code defines it) of each bar. The program also automatically calculates the buckling length of the bars according to an approximate method, based on commonly accepted formulae, which requires for the user to classify the structure as a sway frame or a non-sway frame.

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.
Concrete, rolled steel, cold-formed steel, aluminium and generic material (by specifying the modulus of elasticity and Poisson’s ratio). The density of the mesh can be controlled by defining the maximum size of the triangle in the local x and y axes.
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. 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 baseplate design options are configured in the Options dialogue box (Baseplates > Options).
In IFC files, the structural analysis model is composed of structural type entities, such as nodes, bars, loads, etc. More information on the importing of IFC files can be found in the IFC file import section of the New features of the 2012 version in CYPE 3D and Integrated 3D structures. Manages the object snap settings for snapping to entities and elements of the DXF or DWG visualised in the 2D windows of the job.
More information on these modules and a comparative study displaying the analysis duration with and without their use can be found in the Analysis using multiprocessors page.

These ties are used to indicate that two or more nodes have the same displacements for all the loadcases.
They can be defined as made of steel (rolled, welded or cold-formed), aluminium, timber, concrete or any other user-defined material (modulus of elasticity, Poisson’s ratio, coefficient of thermal expansion and unit weight). To check and design reinforced concrete bars in CYPE 3D, they must be defined as Column-type or Beam-type structural elements.
Transverse sections that can be assigned this type include flat bars, angles, solid round or square bars. Nonetheless, the program allows users to define continuous beams composed of several beams.

Generally speaking, each code offers values for these coefficients associated to different bending moment distributions. Shells are flat two-dimensional elements with constant thickness and without openings, whose perimeter is defined by a polygon. 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 possible external fixity configurations are the same as those available for the nodes of CYPE 3D. The connection relationship between the nodes and bars is also defined using fixity conditions. This way, the user can introduce the nodes and bars of the structure by snapping to the entities and elements of these files in the 2D windows of the program. Displays the colours which differentiate the elements of the 3D view even if it consists of the same material. This location is the easiest way to see the best picks from our warehouse, without getting dust on your clothes.

The import process and use methodology of the DXF and DWG files is the same as in CYPECAD. A reference number, applied to each group of nodes whose displacements are tied, is displayed on screen.
Flat trusses with hollow structural sections) can be used in CYPECAD and CYPE 3D (including the Integrated 3D structures of CYPECAD).
