With the RFEM 5.04.0024 and RSTAB 8.04.0024 versions, you can define the antenna ice loads in RF‑/TOWER Loading. The program provides the values from the manufacturer databases. In addition, you can define the ice loads manually or use the calculation based on simplified geometry.
RF-/CONCRETE automatically determines the minimum concrete cover according to the standard. The calculation is based on the exposure class, the abrasion class, and the concrete cast.
The updated Results Navigator of RF‑JOINTS allows you to display the results of different module cases simultaneously. Thus, you can display all column base designs at the same time in order to perform collision checks of the foundations, for example.
In RFEM, there are a file‑based and a direct DXF interface. The file-based DXF interface allows you to export the data in a DXF file that is transferred directly into an open AutoCAD file. In the interface dialog box, you can select which data are to be exported (results as isolines, result values, or finite element mesh with boundary and integration lines).
In RFEM, you can simulate a scaffolding tube joint (butt joint with a stub) by a nonlinear member release of the "Scaffolding" type. The joint considers moment resistance dependent on compression forces existing between two outer tubes, and the stub also has certain moment resistance based on its bending resistance.
In his bachelor's thesis, Jonas Mösch analyzes the open and closed interfaces in BIM-based structural design. The theoretical section covers the definition of the term "Building Information Modeling".
Due to the structural efficiency and economic benefits, dome-shaped roofs are frequently used for storehouses or stadiums. Even if the dome has the corresponding geometrical shape, it is not easy to estimate wind loads due to the Reynolds number effect. The external pressure coefficients (cpe) depend on the Reynolds numbers and on the slenderness of the structure. EN 1991‑1‑4 [1] can help you to estimate the wind loads on a dome. Based on this, the following article explains how to define a wind load in RFEM. Wind loads of the structure shown in Image 01 can be divided as follows: Wind Load on Wall, Wind Load on Dome.
When designing column bases, high-performance anchors are often used for an anchorage. This article describes different models for a column footing and the evaluation thereof.
As of program version x.06.1103, you can enter a soil profile in RF‑/FOUNDATION Pro. This gives you the advantage of setting several soil layers with different soil parameters above and below the foundation base. To enter the soil layers, there is a library with various soil types that can also be extended with user‑defined soils. The user-defined soil profile is shown in an interactive information graphic. Any change (for example, a soil thickness modification) is reflected in the graphic immediately.
This post describes two practical examples, based on the Eurocodes, where the reduction of combinations is reasonable. There are a large number of various National Annexes as well as several material standards (EC 2 to EC 9) that are not in compliance with the rules for structural design (EC 0).
