Modeling Tapers for Hall Frames

Tips & Tricks

Tapers are often done using cut beam sections. When modeling, however, you have to consider some things for the checks of cross‑sections and stability.

First, the start and end cross‑section must have the same number of stress points, that is, the same cross‑section shape. For example, it is not possible to define the section at the start as I‑section and at the end as cut beam section.

Furthermore, you have to consider for the general method according to EC 3 that in some countries only I‑sections are allowed for this purpose.

Therefore, it is generally recommended to specify tapers as parameterized I‑sections (IS). The sheet thicknesses can be imported directly from the rolled cross‑sections (see Figure).
