Dlubal - Professional Software for Structural Analysis & Design

Dlubal - BIM ready software for structural analysis of steel, reinforced concrete, timber and aluminium structures in civil, plant and mechanical engineering, glass design and dynamics.

Dlubal Software company has been involved in the development of user-friendly and powerful programs for structural and dynamic calculations and analyses as well as for designs of framework structures.

User-friendliness and effectiveness of our structural analysis software as well as the professional technical support for our customers are the fundamental pillars of the Dlubal Software company philosophy.


RFEM 5 - Professional Structural FEA Program

The finite element analysis program RFEM is a powerful software for quick and easy modeling, structural analysis and design of 2D and 3D models consisting of member, plate, wall, folded plate, shell and solid elements. Due to the modular software concept, you can connect the main program RFEM with the corresponding add‑on modules in order to meet your individual requirements.


Dlubal RFEM - Powerful, Easy, and Intuitive FEA Software

The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

RFEM provides deformations, internal forces, stresses, support forces, and soil contact stresses. The corresponding add-on modules facilitate data input by automatic generation of structures and connections or can be used to perform further analyses and designs according to various standards include Euro Code with Malaysia National Annexes.

RSTAB - Structural Frame Analysis Program

The 3D structural frame analysis program RSTAB is the ideal tool for the design of beam structures consisting of steel, reinforced concrete, timber, aluminum, or other materials.

With RSTAB you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. For further design, there are various add‑on modules available, considering structural data of specific materials and standards.

Dlubal RSTAB - Powerful and Easy to Use

RSTAB is the basis of a modular software system and provides intuitive modeling of simple and complex structures due to it's ingenious input technique. The efficient RSTAB solver allows for linear and nonlinear calculations of internal forces, deformations, and support reactions.

For further designs, there are the add-on modules available, considering structural data of specific materials and standards. Due to the modular software system, you can combine various products of Dlubal Software in a program package that meets your individual needs.

RX-TIMBER - Structural Analysis Software for Timber Structures

The stand‑alone program package RX‑TIMBER designs glued‑laminated beams, continuous beams, and columns at the ultimate and the serviceability limit state according to the timber standard EN 1995‑1‑1:2010‑12/NA:2013‑08 (EC 5) and DIN 1052:2008‑12 .

In addition, it is possible to perform fire resistance design according to EN 1995‑1‑2 or DIN 4102, Part 22.

COMPOSITE-BEAM - Analysis and Design of Composite Structures

A structural member composed of two or more dissimilar materials joined together to act as a unit. An example in civil structures is the steel-concrete composite beam in which a steel wide-flange shape (I or W shape) is attached to a concrete floor slab. The many other kinds of composite beam include steel-wood, wood-concrete, and plastic-concrete or advanced composite materials–concrete.Composite beams as defined here are different from beams made from fiber-reinforced polymeric materials.

The Dlubal COMPOSITE-BEAM program performs design of composite beams according to:
ENV 1994‑1‑1:1992‑10

The program is based on bidirectional communication between RSTAB and the add‑on modules. However, an RSTAB license is not required for using COMPOSITE‑BEAM (stand‑alone operation is possible).

SHAPE-THIN and SHAPE-MASSIVE - Programs for Cross-Section Values

Stand-alone programs for determining cross-section properties of any type of cross-section, as well as calculation of stresses and design.

Both programs have a connection to RSTAB and RFEM so that cross-sections from SHAPE-THIN and SHAPE-MASSIVE are available for selection in the libraries of the main programs. Of course, it is possible to import also internal forces from RSTAB and RFEM to SHAPE-THIN and SHAPE-MASSIVE for further design.

BIM Planning

BIM (Building Information Modeling) is an efficient working method for the planning and realization of buildings, which is based on a network of all participants in the building process.

All relevant building data is included in a 3D model, which is then used throughout all of the planning stages. In this way, it is not necessary to use different models created in various CAD and structural analysis programs, but the same model, which can be directly transferred between the programs.

Dlubal RFEM and RSTAB allow for a BIM-oriented planning. Both programs have high-performance interfaces with the leading software tools for computer-aided design and structural analysis. The interfaces are integrated in the programs by default and subject to constant updating and continuous development.

  • Efficient teamwork for engineers planning design and details
  • Working on 3D model with material and geometry information
  • Direct interfaces with Autodesk Revit Structure, Tekla Structures, AutoCAD, and Bentley ISM
  • Keeping intelligence of objects during data transfe
  • Easy transfer of model modifications
  • Standard file formats for data exchange like DXF, IFC, DSTV, STP, SDNF, etc.
  • Interfaces with CAD reinforcement programs of Glaser, Strakon and Nemetschek.
