Abstract
In many applications hollow core units are subjected to
combined torsion and shear. The present calculation
method adds stresses from various effects linearly. Here,
advanced non-linear finite element modelling methods were
developed and verified against full-scale tests, both for
whole floors, and for individual hollow core units. By
combining these two modelling methods, it is possible to
design hollow core floors with arbitrary geometries and
loadings for shear and torsion. Compared to the
traditional approach the modelling method for units
resulted in higher capacities for most ratios of shear
and torsion and the floor model showed reduced torsional
moments.
