Wölbkrafttorsion in exzentrisch beanspruchten Sandwichelementen.

Warping torsion in eccentrically loaded sandwich panels Currently, there is a growing interest in the application of sandwich panels subjected to both torsional and bending stresses. This is particularly relevant for façades when sandwich panels are equipped with photovoltaic panels or a supplementary curtain wall. Nevertheless, technical approval is currently dependent on the performance of sophisticated full‐scale tests, as a mechanically based or standardized calculation approach is not yet available for practical applications. This article provides a detailed analysis of the structural behavior of eccentrically loaded sandwich panels. A comprehensive series of experimental, numerical, and analytical studies were conducted on sandwich wall panels with a polyisocyanurate (PIR) core across a wide range of material‐specific and geometric parameters. The experimental data was employed to assess the validity and reliability of the finite element model and the analytical calculation model based on warping torsion. The core of the work is a parameter study based on this. The results prove the general applicability of warping torsion in sandwich panels within the specified limits and provide the foundation for a novel, practical approximation method for stress and deformation calculations.
