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.

Nyckelord: hollow core slab, shear and torsion interaction, nonlinear finite elment analyses, shear-torsion capacity
