The following technical article describes the creation of a user-defined platform for use on a four-sided tower in the RF-/TOWER add-on modules. First, start with an empty model of the 3D type and define four nodes. The numbering and position of these nodes are very important here.
In the RFEM 5.04.0024 and RSTAB 8.04.0024 versions, there is a new feature in RF‑/TOWER Loading that allows you to define additional surface loads in a load case for dead loads; for example, from grids on platforms.
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-/TOWER load was extended with force coefficients for rounded profiles of four-sided towers and square-edged profiles of three-sided towers. The force coefficients for rounded profiles are determined using the Reynolds number. Previously, you could only use the rounded profiles for four‑sided towers and the square‑edged profiles for three‑sided towers.
