Concrete Structures

The structural engineering FEA software RFEM and the frame analysis program RSTAB provide the possibility to analyze and design reinforced concrete structures. Whether you are dealing with a beam or frame structure (RSTAB) or also with plates, walls, shells, or solids (RFEM), you can choose the corresponding Dlubal Software product. In addition, RFEM allows for structural analysis and design of prestressed concrete structures.

Steel Structures

The structural engineering FEA software RFEM and the frame analysis program RSTAB with steel add-on modules are the optimal solution for the analysis and design of steel structures such as buildings, halls, scaffolding, bridges, silos, cranes, craneways, towers, conservatories, and many others.

Timber Structures

The structural engineering FEA software RFEM and the frame analysis program RSTAB are ideal for modeling, analyzing and designing the 3D timber structures. Whether you design beam structures or surface elements such as cross‑laminated timber plates, there are various options for simple and complex structures.

In addition, the RX‑TIMBER program family provides tools for fast and effective calculation and design of models such as glulam trusses, frames, purlins, and more.

Mechanical Engineering

Many users of Dlubal Software programs perform engineering calculations in RFEM and RSTAB. The finite element analysis (FEA) software RFEM analyzes very complex structures consisting of numerous surfaces, beams, and solids.

Therefore, RFEM is frequently used to analyze details and connections of a structure. In RSTAB, it is possible to design beam, frame or truss structures in an easy and time‑efficient way.

Industrial and Plant Engineering

RFEM and RSTAB are ideal for structural design and analysis of industrial constructions such as chemical plants, production halls, containers, pipeline systems, large filters, and so on. RSTAB allows for design of member structures and RFEM for additional plate, wall, shell, and solid elements.

Piping Systems

RFEM allows modeling of piplines (including piping components such as valves, reducers, flanges, tees and others) and perform piping design.

Piping analysis can be performed for the entire structure, that is in interaction with the support structure.


Many users rely on RFEM and RSTAB when analyzing and designing bridges consisting of steel, reinforced concrete, timber, or other materials.

By using the helpful add-on modules, it is possible to generate for example influence lines, moving loads on members and surfaces, and more. Dynamic analyzes are also possible as well as required designs of stability, serviceability limit state, fatigue and buckling.

Cranes and Craneways

Due to the possibility of 3D modeling, RFEM and RSTAB are ideal for design of cranes. The detailed analysis is supported with features such as consideration of member and release nonlinearities, cable pulleys, and so on.

The stand-alone program CRANEWAY designs runway girders of bridge and suspension cranes according to the standard EN 1993-6, including all required designs.

Towers and Masts

It is possible to design lattice towers with RFEM and RSTAB. The corresponding add-on modules provide a wide range of options, from the automatic generation of structures and loading to the determination of effective lengths and design according to Eurocode. It is also possible to model and analyze individual tower and mast structures.

Power Plants

The structural engineering programs RFEM and RSTAB are ideal for structural analysis and design of power plants. It is possible to combine different materials in the analytical model.

In addition to ultimate limit state design and stability analysis, the programs also perform dynamic analysis.

Glass Structures & Facades

In RFEM, it is possible to analyse and design of glass structures and facades separately or as a part of the entire model. The extensive material library contains a large number of commercially available glass types, foils and gases.

Glass surfaces defined in RFEM can be supported on lines and nodes and even modeled as special solids. The results include surface and solid stresses, among other things.

Tensile Membrane Structures

The structural analysis software RFEM allows for form-finding and design as well as cutting of tensile membrane structures.

The calculation is performed according to the large deformation analysis.

Laminate and Sandwich Structures

In RFEM, it is possible to perform stress and deflection analysis of general laminate and sandwich surface structures. The calculation considers shear coupling and is carried out in compliance with the laminate theory.

It can be applied to the design of cross-laminated timber plates (CLT), fiber-reinforced plastics (for example FRP, GRP, GFRP, carbon material) and many others.

Hydraulic Steel Engineering

RFEM allows for design and analysis of very complex structures containing many surfaces and solids.

Therefore, it is perfectly suited for static and dynamic analysis of hydraulic steelworks like sluices, locks and lock chambers, water gates such as roller, sliding and sector gates, weir flaps, drum gates, flood protection gates, ship lifts, canal bridges, and many others.
