Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

For the stability verification of members using the equivalent member method, it is necessary to define effective or lateral-torsional buckling lengths in order to determine a critical load for stability failure. In this article an RFEM 6-specific function is presented, by which you can assign an eccentricity to the nodal supports and thus influence the determination of the critical bending moment considered in the stability analysis.

Large-scale models are models which contain multiple dimensional scales and thus are demanding on computational power. This article will show you how to simplify and optimize the calculation of such models with respect to the desired results.

With the Steel Design add-on, you can design structural steel components in the event of fire using the simple design methods according to Eurocode 3. The component temperature at the time of the design check can be determined automatically according to the temperature-time curves specified in the standard. In addition to considering a cladding for fire protection, it is also possible for you to take account of the beneficial properties of hot-dip galvanization.

Custom sections are often required in cold-formed steel design. In RFEM 6, the custom section can be created using one of the “Thin-Walled” sections available in the library. For other sections that do not meet any of the 14 available cold-formed shapes, the sections can be created and imported from the standalone program, RSECTION. For general information on AISI steel design in RFEM 6, refer to the Knowledge Base article provided at the end of the page.

Steel connections in RFEM 6 can be created by simply entering predefined components in the Steel Joints add-on. The collection of these components is constantly being improved to make your work even easier even when modeling steel connections. In this article, the connection plate component is introduced as a component recently added to the add-on's library.

It is possible for emergency situations to create challenging working conditions for Urban Search and Rescue (USaR) workers. The important goal is to achieve a significant time reduction in relation to the Urban Search and Rescue (USaR) phase by delivering wide-area situation awareness resolutions for improved detection and localization of the trapped victims, aided by simulation tools for predicting structural failures, as well as a holistic decision support mechanism that incorporates the operational procedures and resources of relevant actors.

RFEM 6 offers the Aluminum Design add-on for the design of aluminum members. This article shows how class 4 sections are designed according to Eurocode 9 in the program.

In RFEM 6, the results for the FE mesh nodes are determined using the finite element method. For the distribution of internal forces, deformations, and stresses to be continuous, these nodal values are smoothed through an interpolation process. This article will introduce and compare the different types of smoothing that you can use for this purpose.

As you may already know, RFEM 6 offers you the possibility to consider material nonlinearities. This article explains how to determine internal forces in slabs modeled with nonlinear material.
