Shear and torsion interaction of hollow core slabs (HOLCOTORS)

Objective

Precast pre-stressed hollow core slabs are among the most advanced and widely spread products in the precast concrete industry. The present design method for shear and torsion in Euro code 2 and preen 1168 is conservative and hence an obstacle for competition, since no interaction is taken into account. The project will develop a design method for this interaction. The program includes a modelling of the phenomenon using non-linear fracture mechanics in finite element analysis, both for individual elements and total floors, validated by tests. The resulting design method and parameters will be directly used in the CEN product standard prEN 1168, and benefit the entire European precast concrete industry (189000 people in 5000 plants). The pre-normative study is strongly supported by the CEN/TC229 resolution N° 118.
