The experimental model consisted of a full-scale 3-storey building withslabs made up of reinforced concrete. In addition, the construction process included anintermediate stage during striking, known as clearing (partial striking). The technique consistsof removing the formwork and 50% of the shores which hold up the slab, a few days after thepouring of concrete. From the experimental study, it has been demonstrated that afterclearing, a significant part of the loads (self weight) are transferred to slabs. Additionally afinite model has been developed to simulate construction process of the experimentalstructure. The finite element model has been calibrated by comparing experimental andnumerical results.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 322
