Abstract:The paper describes the development of models for torsion in northern Europe. After an introduction with a few historical notes, early use of nonlinear
methods in Scandinavia is presented. The development of failure models for combined torsion, bending and shear is then described as well as the use of truss models. Static and kinematic methods are treated and a discrepancy in the results from different approaches is discussed. A refined model is then presented which unifies the results. Finally, some recent contributions are presented regarding prestressed high-strength circular column elements, hollow core slabs and curved bridges.
