Structural analysis and design software for timber structures

Structural Analysis of Timber Structures

The structural analysis programs RFEM and RSTAB are ideally suited for the structural analysis and design of two- or three-dimensional timber structures such as B. Timber trusses, timber frames, trusses, glulam trusses, timber sandwich panels, timber panel walls, timber houses, timber bridges, timber towers, timber stairs.

Whether you design beam structures or surface elements, such as cross‑laminated timber plates, there are various options for simple and complex timber structures.

  • Membrane Roofing
    The combination of glued-laminated timber and steel is ideal for many interesting projects. The membrane roofing of a grandstand on the banks of the Elbe in Dresden, Germany, for more than 200,000 guests is an example of this.

    The structural analysis program RFEM alows for structural engineers to efficiently perform structural analysis of timber and steel membrane structures.

  • Stairway Structure
  • Pedestrian Bridge

    Many users rely on structural analysis software RFEM (FEA) and RSTAB (frames and trusses) when analyzing and designing timber bridges.

    Timber bridges have a long tradition and especially in recent years, they are becoming increasingly popular. In addition to the high performance, economic efficiency and design variety, the sustainability of the timber material is a compelling argument for the bridge construction.

Structural FEM Analysis and Design

The structural analysis program RFEM 6 is the basis of a modular program family. The main program RFEM 6 is used to define structures, materials, and loads of 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.

Structural Frame & Truss Analysis Software

The structural frame analysis software RSTAB 9 has a similar range of functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years it has been the best choice for structural analysis and design.

Wind Simulation & Wind Load Generation

The RWIND 2 stand-alone program is recommended for complex structures. Utilize this program to simulate wind flow (digital wind tunnel) around buildings or any other objects and generating wind loads, that is the forces acting on these objects based on CFD.

Import the generated wind loads acting on these objects to the structural analysis and design software RFEM or RSTAB.

Timber Design According to Various Standards

The Timber Design add-on for RFEM 6 / RSTAB 9 designs timber members for the ultimate, serviceability, and fire resistance limit state according to the standards

  • European Union EN 1995-1-1:2010 (Eurocode 5)
  • Switzerland SIA 265:2015-08 (Swiss standard)
  • United States ANSI/AWC NDS:2018 (US standard)
  • Canada CSA 086 (Canadian standard)
  • People's Republic of China GB 50005 | 2017-11 (Chinese standard)

Analysis and Design of Laminate Surfaces

The RF-LAMINATE add-on module for RFEM 5 determines stiffness and performs stress and deflection analysis of laminate surfaces (for example, cross-laminated timber panels).

Design of Timber Connections

Numerous add-on modules provide design options for steel and timber connections.

Stand-Alone Programs RX-TIMBER

Stand-alone programs RX‑TIMBER perform the design of the ultimate limit state, the serviceability limit state and the fire resistance according to Eurocode 5.

Generation, Analysis, and Evaluation of Building Models

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

Consideration of Construction Stages

The Construction Stages Analysis (CSA) add-on for RFEM 6 allows you to consider the construction process of structures (member, surface, and solid structures). Neglecting the influence of the construction process can lead to errors in the calculation of overall models. With the Construction Stages Analysis (CSA) add-on, you can analyze these influences and consider them up to the point of the structural design.

Model Optimization Using Artificial Intelligence (AI)

The two-part Optimization & Costs / CO2 Emission Estimation add-on for RFEM 6 / RSTAB 9 finds suitable parameters for parameterized models and blocks using the artificial intelligence (AI) technique of particle swarm optimization (PSO) to comply with common optimization criteria. Moreover, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.

Interfaces for Data Exchange

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

The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
