Entering Lateral Supports and Their Effects in RF-/STEEL EC3
When designing steel columns or steel beams, it is usually necessary to carry out cross-section and stability analyses. In most cases, cross-section design can be carried out without giving further details; the stability design, however, needs additional user-defined specifications. To a certain extent, the member is cut out from the structure and therefore, the support conditions have to be specified. This is particularly important to determine the ideal critical moment for lateral torsional buckling Mcr. In addition, the correct effective lengths Lcr have to be defined. They are necessary for the internal calculation of the slenderness ratios. -
Stability Analysis of Steel Column According to EN 1993-1-1
This article is about the stability analysis of a steel column with axial compression according to EN 1993-1-1 Clause 6.3.1. Additionally, a variation study is carried out aiming at steel optimization. -
Load Combinations in Timber Structures for European and American Timber Standards
In addition to determine loads, there are some particularities concerning the load combinatorics in timber design which have to be considered. Contrary to steel structures where the largest loading results from all unfavorable actions, in timber construction, the strength values are dependent on the load duration and the timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.

Wind Load on Monopitch and Duopitch Roofs in Germany
In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m. -
Cross-Section Design of Two-Span Beam
The cross-section class of a two-span beam will be designed in the following. In addition, the necessary cross-section designs will be performed. The global stability failure will be excluded due to sufficient stabilizing measures. -
Modeling a Girder Grillage
The structural analysis of a girder grillage is usually no big deal when using computer-aided calculation. There are different options to display and analyze a structure. They include, for example, the conventional way with performing structural analysis of components or modeling the entire structure. -
Determination of Bearing Resistance with "Drained" and "Undrained" Soil Conditions
The RF-/FOUNDATION Pro add‑on module designs single foundations (foundation plates, bucket and block foundations) for all support forces arising in the RFEM/RSTAB model. The geotechnical designs are performed according to EN 1997-1. -
Determination of Wind Loads for Canopy Roof Structures According to EN 1991-1-4
If a canopy roof, for example a filling station roof, should be designed, a load determination having regard to Section 7.3 of EN 1991-1-4 is required. This article shows with an example the design of a slightly inclined troughed roof. -
Consideration of P-Delta Effects (Second-Order Analysis) in the Response Spectrum Analysis According to ASCE 7-16
RFEM offers the option to perform a response spectrum analysis according to ASCE 7-16. This standard describes the determination of seismic loads for the US-American market. It might happen that the so-called P-Delta effect has to be considered due to the stiffness of the entire structure to be able to calculate the internal forces and carry out the design. -
Determination of Effective Lengths in RF-/CONCRETE Columns
With RF-/CONCRETE Columns, it is possible to determine effective lengths for columns automatically. This article describes which entries are necessary and how the calculation of the effective lengths is carried out.
