Designing Reinforced Concrete Compression Elements Subjected to Biaxial Bending with the Nominal Curvature Method
Daily tasks in reinforced concrete design also include designing compression elements subjected to biaxial bending. The following article describes the different methods according to Chapter 5.8.9, EN 1992-1-1, which can be used to design compression elements with biaxial load eccentricities by means of the nominal curvature method according to 5.8.8.

Elastic-Plastic Cross-Section Design
The following article describes designing a two-span beam subjected to bending by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-1. The global stability failure will be excluded due to sufficient stabilizing measures.

Differences Between the Analytical and Nonlinear Deformation Analysis of Reinforced Concrete
Different methods are available for calculating the deformation in the cracked state. RFEM provides an analytical method according to DIN EN 1992-1-1 7.4.3 and a physical-nonlinear analysis. Both methods have different features and can be more or less suitable depending on the circumstances. This article will give an overview of the two calculation methods.

Calculating Timber Panel Walls | 1. Determining the Ultimate Limit State and Stiffness
The stiffening of timber structures is usually carried out by means of timber panels. For this purpose, structural components consisting of slabs (chipboards, OSB) are connected with members. Several articles will describe the basics of this construction method and the calculation in the RFEM program. This first article describes the basic determination of the stiffnesses as well as the calculation.

Exporting Spring Stiffnesses from RF-/FOUNDATION Pro and the Influence on Column Design
With RF-FOUNDATION Pro, it is possible to determine settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.

The Benefits of BIM in Structural Analysis
Building Information Modeling hits the headlines in building design. While some engineers only use BIM methods for planning, others deal with this topic for the first time or hardly have time for it in their daily working routine. However, one topic seems to be the most important in structural engineering: How can structural engineers benefit from BIM?

Internal Forces Diagram/Surface Stresses - Smoothing Options
The deformations of the FE nodes are always the first result of an FE calculation. Based on these deformations and the stiffness of the elements, it is possible to calculate strains, internal forces, and stresses.

Comparing Critical Load Factors for Lateral-Torsional Buckling According to Different Methods and Modules
The critical factor for lateral-torsional buckling or the critical buckling moment of a single-span beam will be compared according to different stability analysis methods. -
Nonlinear Time History Analysis Using the Example of a Tower Structure with Prestressed Cables
There can be numerous nonlinearities in a structural system. In order to model them realistically in a dynamic analysis, the RF-DYNAM Pro - Nonlinear Time Histoey add-on module was developed. To explain how the add-on module works, the procedure is described below with an example.
