In recent years, hybrid towers have become increasingly established, especially for large wind turbines. The concrete component of these towers, commonly constructed using segmental construction methods, consists of several circular ring segments stacked on top of each other. In addition to the horizontal joints, vertical joints divide the segments into even smaller components. This leads to a complex load-bearing behavior that has not been fully understood yet. This article presents a literature review on hybrid tower structures using concrete circular ring segments divided into smaller components by vertical joints to form half, third and quarter shells. Additionally, this paper provides a summary of an analytical modelling approach developed by Klein and Marx, which describes the torsional load-bearing behavior of segmented concrete towers based on the warping theory of thin-walled beams. The analytical modelling approaches are applied to test segments on a scale of 1:5. Furthermore, non-linear numerical analyses are conducted. The calculations serve as a basis for the comprehensive experimental tests carried out on model concrete segments.
