The model describes a comprehensive time history analysis of a pedestrian bridge where RF-DYNAM Pro is used to simulate and evaluate dynamic loads from walking and running. Detailed time series are presented to capture vibration and response patterns. This study provides accurate insights into the frequency response of the bridge structure and helps to identify influencing factors in dynamic behavior. The representation allows engineers to perform informed analyses for optimizing bridge designs. The article includes all relevant parameters for simulation and evaluation in the context of bridge traffic.

This article provides a comprehensive overview of essential seismic analysis methods, explaining their principles and applications, as well as the scenarios in which they are most effective
For reinforced concrete components and structures with structural behavior considerably influenced by the effects of the second-order analysis, Eurocode 2 provides the general method based on a nonlinear determination of internal forces according to the second-order analysis (5.8.6), as well as the approximation method based on the nominal curvature (5.8.8).
The aim of this technical article is to perform a design according to the general design method of Eurocode 2, using the example of a slender reinforced concrete column.

This article provides a step-by-step guide to the design of shear walls in RFEM 6.
This technical article shows you how the "Concrete Foundations" add-on in RFEM 6 facilitates the execution of geotechnical design checks. For the design of a foundation according to DIN EN 1997-1/NA, a structural system consisting of a concrete column with a foundation slab is considered. The essential design checks for ground failure safety, sliding resistance, highly eccentric loads in core (limitation of the gaping joint), and highly eccentric loading are presented and illustrated.

The "Nonlinear Material Behavior" add-on includes the Anistropic | Damage material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.
You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.
For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.
It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.
In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (wk).
For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.
For concrete design, you can display the reinforcement results in tables separately by design situation.
When opening an RFEM file, the entries in RF‑CONCRETE Surfaces are lost. Is this possible?
How can I understand the calculation of the required reinforcement?
I have created a model in which the ceiling slab is lined with ribs. When I assign a Rib member type to the boundary line of the surface and align it to the bottom edge of the surface, the boundary line is automatically pulled towards the center of gravity of the rib, that is, downwards under the slab. Is there a way to change this so that my lines still appear at the edge of the surface?
Is it possible to view the tangential and radial analysis results and reinforcement requirements rather than orthogonal for a circular slab?
How can I perform member design by case for different settings in the design configuration?
Why do I only obtain the total reinforcement in the Results navigator under "Required Reinforcement", and no result for the top and bottom reinforcements separately?
