CP 001193 | Hobro Arrest Prison Scaffolding, Denmark

The scaffolding structure consists of aluminum trusses with heights varying between 1.64 ft and 3.28 ft as well as horizontal steel beams, columns, railings, and bracings. All elements are based on the PlusEight system.

Example
When calculating a surface model, the internal forces are determined separately for each finite element. Since the element-by-element results usually represent a discontinuous distribution, RFEM performs smoothing of the internal forces that takes into account the influence of adjacent elements. The discontinuous distribution of internal forces is adjusted with this method. The result evaluation is thus clearer and easier.
Example 1
When evaluating line support forces, implausible diagrams sometimes arise at first glance. In particular, for variable loads at locations that also have a nodal support, at division points and edge locations of supported lines, the results sometimes show unexpected support reactions. Using the function of the linear smooth distribution in Project Navigator – Display does not always lead to the expected result diagram.
Structural Modeling in RFEM
When introducing and transferring horizontal loads such as wind or seismic loads, increasing difficulties arise in 3D models. To avoid such issues, some standards (for example, ASCE 7, NBC) require the simplification of the model using diaphragms that distribute the horizontal loads to structural components transferring loads, but cannot transfer bending themselves (called "Diaphragm").
Building Model in IFC Viewer (Bottom) and Calculated Model in RFEM (Top)
The calculation of structures based on digital twins is becoming an everyday task in the engineering office. If a digital building model already exists, you want to continue to use the information contained in it as seamlessly as possible. This places far-reaching demands on modeling and interfaces for BIM-compatible structural analysis software.

Activation of Camera Flight Mode in RFEM

With the Camera Fly Mode view option, you can fly through your RFEM and RSTAB structure. Control the direction and speed of the flight with your keyboard. Additionally, you can save the flight through your structure as a video.

Result Table with Colored Relation Scales

The result tables show in color whether the internal forces are positive or negative, as well as showing the relation to the extreme values. The result tables of the design modules use color scales to represent the respective design ratios. This way, the governing locations are apparent immediately.

Feature 002426 | Animation of Deformation

The deformation process of the global deformation components can be represented as a movement sequence.

Feature 002421 | Displaying Result Values on Isolines

Result values for deformations, internal forces, stresses, and so on, can be displayed on the isolines.
