Have a look at the new features and new add‑on modules in the current customer version of RFEM/RSTAB.
Moreover, you can find useful technical articles as well as tips & tricks on the ‘Product Features’ page.
The structural engineering programs RFEM and RSTAB are the optimal solution for the analysis of steel and metal structures such as buildings, halls, scaffolding, bridges, silos, cranes, craneways, towers, conservatories, and many others.
The modular concept of the Dlubal Software products consists of the main program RFEM or RSTAB and the corresponding add-on modules.
Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, members (beams), solids, and contact elements.
Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, and truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.
RF-/STEEL performs general stress analysis of members and surfaces by calculating the existing stresses and comparing the results with limit stresses.
The following add‑on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as deformation analyses for structural steel.
RF‑/STEEL Warping Torsion is an extension of the RF‑/STEEL EC3 add‑on module. It performs torsional‑flexural and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.
RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module. It allows for plastic design of cross‑sections according to Partial Internal Forces Method or Simplex Method.
RF-IMP/RSIMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.
RF-/STEEL Fatigue Members performs fatigue design of members (beams) and sets of members in compliance with the standard EN 1993‑1‑9.
CRANEWAY calculates and performs all required designs of craneway girders according to Eurocode 3. Optionally, you can select bridge or suspension crane.
Stand-alone software PLATE‑BUCKLING or add-on modules RF‑/PLATE‑BUCKLING perform plate buckling analysis of rectangular plates according to EN 1993‑1‑5.
Stand-alone cross‑section analysis software SHAPE‑THIN determines cross-sectional properties, performs stress analysis and plastic design of any thin-walled cross-section. It is possible to export cross-section and calculated section properties to main programs RFEM or RSTAB.
Add-on modules for dynamic analyses are suited for seismic design, vibration analysis of buildings, machine foundation design, natural frequency analysis for bridges and chimneys, and many other dynamic calculations.
Here you can find numerous add-on modules for the design of joints in steel and timber structures.
A unique structure called Sky Walk has been built at a height of 1,116 m under the Králický Sněžník mountain in the Czech Republic and is unprecedented in Central Europe.
The Sky Walk is a look‑out trail leading up to 58.5 m above the surrounding hilly terrain level, being visible at a distance of several kilometers.
The Ferrari World Theme Park on the Yas Island, UAE, is an amusement and recreation park including the Formula 1 racing circuit, a shopping mall, several luxury hotels and two golf courses.
The gigantic free-formed roof of the Ferrari World is the largest spatial framework ever built.
The multifunctional two-tier stadium with 30,000 seats was built in Uyo, Nigeria.
The stadium with the ornamental façade consists of two separate steel structures - the stand area with rounded corners and the VIP box.
Because of modernization and increased passenger capacity, the third terminal was built at the Sheremetyevo International Airport in Moscow, Russia.
The 3D model consists of several arched roofs and a pedestrian bridge suspended from the main arc.
From architectural point of view, the most impressive structural component of the extended shopping mall Centrum Černý Most in Prague, Czech Republic is the partially glazed roof over the food court.
This is where the design of the featured steel structure found its use.
The steel structure of the roof above the northern gate of Frankfurt Exhibition Grounds has an oval shape with a size of 42 m x 18 m.
The roof is supported by pyramid-shaped columns, which appear particularly slim and the roof has the illusion that it is floating.
In Chile, a very extraordinary structure was finished at the end of 2014: It is the "temple of light" which is one of eight Bahá’í temples worldwide.
The unique building resembles a nine‑petalled blossom of a lotus flower.
The new BVB-FanWelt at the Signal Iduna Park in Dortmund, Germany, was opened to use the open and generously designed building for merchandising.
Also, it gives the fans of the Borussia Dortmund football team (BVB) the possibility to discover and experience for example the stylized south stand, the legendary "yellow wall".
The cross-section properties software SHAPE-THIN determines effective section properties of thin-walled cross-sections according to Eurocode 3 and Eurocode 9. Alternatively, the program allows for plastic design of general cross-sections according to Simplex Method. In this process, plastic cross-section reserves are iteratively calculated for elastically determined internal forces.
The following example describes the effective cross-section properties in the notching area of a rolled I-section. Afterwards, the results are compared with the plastic analysis.
A structural analysis does not only determine and design internal forces and deformations. It also ensures that the forces and moments in a structure are generated in a reliable way and applied to the foundation. Dlubal Software provides a wide range of products for structural analysis and design of steel and timber connections. The RF-/JOINTS Steel - Column Base add-on module allows you to design footings of hinged and restrained column bases. The design can be performed for both column base plates with or without stiffeners.
