Numerical validation of an innovative 3D calculation method of high‐rise buildings under consideration of component and soil stiffness

Abstract At the end of the PORR Bau GmbH research project, which ran from 2015 to 2022 and which provided data on strain and settlement sensors from a total of four high‐rise buildings, an innovative calculation method for three‐dimensional building models was finally developed. This is based on a stiffness combination vector that can be applied independently of the finite element program and the modeling quality of the responsible structural engineer. Furthermore, the bedding modulus for supporting the floor slab is varied within the limits specified by the soil expertise by dividing the floor slab into quadrants.
