Nonlinear Dynamic Analysis 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.
The structural frame analysis and design program RSTAB contains a similar range of functions as RFEM, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.
The RF-/DYNAM Pro - Natural Vibrations add-on module performs the analysis of natural frequencies and mode shapes.
RF-/DYNAM Pro - Nonlinear Time History is an extension of the add‑on modules RF‑/DYNAM Pro - Natural Vibrations and RF‑DYNAM Pro - Forced Vibrations (linear time history analysis).
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.
The "Little Flower" monastery was built in 2015, situated in beautiful scenery of green meadows, mountains, and crystal-clear lakes.
The little monastery is equipped with 18 bedrooms, a chapel, a dining room, a kitchen, and a conference room.
A timber apartment complex with appealing architecture has been built in the Italian town of Brescia. Four housing complexes include a total of 72 housing units.
For the Lombard Institute for Residential Buildings (ALER), this was the first project carried out in wood.
The multigenerational house with a lakeside view was built as an environmentally friendly timber structure and designed as a passive house.
The engineering office Pirmin Jung Deutschland GmbH, a customer of Dlubal Software, was in charge of structural analysis, among other things.
The butadiene storage tanks of the French company ARLANXEO Emulsion Rubber France, one of the biggest producers of NBR synthetic rubber in the world, had to be recalculated to comply with the seismic requirements of Eurocode 8.
In December 2013, a hotel with extraordinary architecture opened in Davos, Switzerland. The building is shaped like a golden egg and is situated on a mountainside.
The hotel is elliptical in shape with all corners rounded, and is constructed with reinforced concrete.
An extraordinary structure was built in Chile: "Temple of Light", one of eight Bahá'í temples in the world.
The shape of the temple resembles a nine‑petalled blossom of a lotus flower. The building has a diameter of about 111.5 ft and a height of 98.4 ft.
One of the world's highest timber structures is a lookout tower on the Pyramidenkogel, a mountain in Carinthia, Austria.
The spiral-shaped tower with a height of 328 ft provides a breathtaking view over the Alps-Adriatic region.
