Analysis of Steel Structures in RFEM 6 | Steel Hall
Knowledge Base Articles
Building Overview (KB1866)
To evaluate whether it is also necessary to consider the second-order analysis in a dynamic calculation, the sensitivity coefficient of interstory drift θ is provided in EN 1998‑1, Sections 2.2.2 and 4.4.2.2. It can be calculated and analyzed using RFEM 6 and RSTAB 9.
The coefficient θ is calculated as follows:$$\mathrm\theta\;=\;\frac{\displaystyle{\mathrm P}_\mathrm{tot}\;\cdot\;{\mathrm d}_\mathrm r}{{\mathrm V}_\mathrm{tot}\;\cdot\;\mathrm h}\;$$
Reduction of Building to Cantilever Structure The individual mass points represent stories. The deflection due to the normal compression forces shown in (a) is (b) converted into equivalent moments of displacement or shear forces (KB1867)
For the ultimate limit state design, EN 1998‑1, Sections 2.2.2 and 4.4.2.2 require a calculation considering the second‑order theory (P‑Δ effect). This effect may be neglected only if the interstory drift sensitivity coefficient θ is less than 0.1.

Product Features
Feature 002807 | 3D Display of FSM Results

In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.

Feature 002806 | Visual Objects

In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.

These objects allow you to create a better reference to the dimensions.

Feature 002793 | Mia, AI Assistant in RFEM

Mia is accessible in the programs and prevents the hassle of following up by email or phone.

Feature 002794 | "Dashpot" Member Type

Using the "Dashpot" member type, you can define a damping coefficient, a spring constant, and a mass. This member type extends the possibilities within the Time History Analysis.

With regard to viscoelasticity, the "Dashpot" member type is similar to the Kelvin-Voigt model, which consists of the damping element and an elastic spring (both connected in parallel).

Frequently Asked Questions (FAQ)
The performance when starting the programs or working in the program has become noticeably worse. What could be the cause of this?
How do I define a plastic hinge in RFEM 6?
How can I exchange data between RFEM 6 / RSTAB 9 and IDEA StatiCa?
How can I adjust the brightness of inactive objects?
Which products do you recommend for the structural analysis and design of reinforced concrete structures?
The calculation in RFEM 6 takes a very long time, but the processor utilization of my system is low. Why is this?
