Project Details


In the building practice it is common to use point supported flat slabs made of insitu concrete. The use of precast elements working as a mould and as the lower structural part of the slab is not handy, because the region arround the column must always be formed by extra fitted formwork. Thus, this project aims at a pre-cast element made of UHPC which replaces the extra mould around the columns and which improves the punching shear performance of the slab. Finite element analyses and full-scale experiments are accomplished for finding the scientific fundamentals
