Time-dependent concrete properties, such as creep and shrinkage, are very important for your calculation. You can define them directly for the material in the structural analysis program. In the input dialog box, the time course of the creep or shrinkage function is displayed to you graphically. You can easily select the modification of the applied concrete age, for example, due to a temperature treatment.

The fatigue design according to EN 1992-1-1 must be performed for the structural components subjected to large stress ranges and/or many load changes. In this case, the design checks for the concrete and the reinforcement are performed separately. There are two alternative design methods available.
Using an example of a steel fiber-reinforced concrete slab, this article describes how the use of different integration methods and of a different number of integration points affects the calculation result.
When it comes to wind loads on building type structures as per ASCE 7, numerous resources can be found to supplement design standards and aid engineers with this lateral load application. However, engineers may find it more difficult to find similar resources for wind loading on non-building type structures. This article will examine the steps to calculate and apply wind loads as per ASCE 7-22 on a circular reinforced concrete tank with a dome roof.

In order to correctly design a downstand beam or a T-beam in RFEM 6 using the Concrete Design add-on, it is essential to determine the flange widths for the rib members. This article describes the input options for a two-span beam and the calculation of the flange dimensions according to EN 1992-1-1.
The structural analysis program provides you with a clear overview of all performed design checks for the design standard. You have to determine a design criterion for each design check. In addition to the ultimate limit state and the serviceability limit state design, the program checks the design rules of the standard. For each design check, there are the design details including the initial values, intermediate results, and final results, arranged in a structured way. An information window in the design details shows you the calculation process with the applied formulas, standard sources, and results in great detail.
You can display the existing stresses and strains of a concrete cross-section and the reinforcement as a 3D stress image or 2D graphic. Depending on which results do you select in the result tree of the design details, the stresses or strains are displayed to you in the defined longitudinal reinforcement under the load actions or the limit internal forces.
Time-dependent concrete properties, such as creep and shrinkage, are very important for your calculation. You can define them directly for the material in the structural analysis program. In the input dialog box, the time course of the creep or shrinkage function is displayed to you graphically. You can easily select the modification of the applied concrete age, for example, due to a temperature treatment.
You determine the deformation for members and surfaces, taking into account the cracked (state II) or non-cracked (state I) reinforced concrete cross-section. When determining the stiffness, you can consider "tension stiffening" between the cracks according to the design standard used.
How can I activate the design with steel fiber-reinforced concrete in the "Concrete Design" add-on for RFEM 6?
Which products do you recommend for the structural analysis and design of reinforced concrete structures?
In the table of the objects to be designed in the Concrete Design add-on, punching nodes are listed in the not valid/deactivated column, although I have defined them as punching nodes. How can I fix this?
How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
How can I use graphic templates for multi printing of a reinforcement?
I use a template for the data exchange with Revit or Rhino/Grasshopper, and get an error message.
