Analysis and Design Software for Concrete Structures

The successful structural analysis program RFEM 6 by Dlubal Software is the basis of a modular program family that you can customize and combine according to your precise requirements.

In the main program RFEM, you can define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Furthermore, you can create combined structures as well as model solid and contact elements.

• Main Program RFEM 6

Use the Dlubal spatial frame & truss analysis software RSTAB 9 if you need a special solution tailored to beam, frame, and truss structures. Due to the special attention to such structures, it is even easier to use than the FEA software RFEM. RSTAB 9 has been the best choice for structural analysis and design of pure structural member models for many years.

• Main Program RSTAB 9

Do your structures have to withstand every gust of wind? Then use the Dlubal stand-alone program RWIND 2. It is particularly recommended for complex model shapes. There are wind flows around all structures simulated in a digital wind tunnel.

You can easily import your generated wind loads acting on these objects into RFEM or RSTAB. Thus, you can continue your project there.

When it comes to reinforced concrete, the Concrete Design add-on for RFEM 6 / RSTAB 9 is your powerful partner. Here you can design members, columns and, with RFEM, also surfaces. Furthermore, you can perform punching shear design and deformation analysis of surfaces in RFEM.

The following standards are integrated in the add-on:

•  EN 1992-1-1:2004 + A1:2014 (Eurocode 2, incl. National Annexes)
•  ACI 318-19 (US standard)
•  CSA A23.3-19 (Canadian standard)
• SP 63.13330:2018 (Russian standard)

The Geotechnical Analysis add-on for RFEM 6 supports your work by determining the soil body to be analyzed by using the properties from soil samples. Achieve a high quality of your structural analysis of buildings due to a realistic determination of the soil conditions (soil-structure interaction).

The Building Model add-on for RFEM 6 allows you to define and manipulate your building by means of stories. A big advantage is that you can adjust the stories in many ways afterwards. Information about the stories and the entire model (a center of gravity) is displayed in tables and graphics.

To keep your buildings safe even under stormy conditions, the Dynamic Analysis add-ons for RFEM 6 / RSTAB 9 are here for you. Use them to perform seismic design, vibration analysis of buildings, machine foundation design, natural frequency analysis for bridges and chimneys, and many other dynamic calculations.

Stay on track of the construction process with the Construction Stages Analysis (CSA) add-on for RFEM 6. In RFEM, this allows you to consider the construction process of structures (member, surface, and solid structures). Avoid potential mistakes when calculating entire models. These may easily arise when disregarding the influence of the construction process. With the helpful add-on, you can analyze the influences and consider them right up to the structural design.

To make your structures to stand the test of time, there is the Time-Dependent Analysis (TDA) add-on available in RFEM. This allows you to consider time-dependent material behavior for members. Long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure.

The two-part add-on Optimization & Costs / CO2 Emissions Estimation for RFEM 6 / RSTAB 9 with the help of artificial intelligence technologies is here for you.  On the one hand, it gives you the suitable parameters for parameterized models and blocks via the artificial intelligence technology (AI) of the particle swarm optimization (PSO) in order to comply with the usual optimization criteria. On the other hand, it estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for your structural model.

Customize RFEM 5 to your project with the RF‑CONCRETE NL add-on module. This module enables you to perform a physical and geometrical nonlinear calculation of beam and plate structures consisting of reinforced concrete. Use the RF‑CONCRETE Deflect add-on module to perform an analytical deformation analysis of plate structures made of reinforced concrete in RFEM 5.

Ensure that your foundation is stable and well-designed. The RF‑/FOUNDATION Pro add-on module for RFEM 5 / RSTAB 8 enables you to precisely design single, bucket, and block foundations for all support forces arising in the model.

• RF-/FOUNDATION Pro Add-on Module for RFEM 5 and RSTAB 8

The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.

Use the Webservice (a programmable interface) to read or write the data from or to RFEM and RSTAB.
