This paper presents the results of tests carried out during the construction of a building of flats with cast-in-place girderless hollow floor slab in Sabadell, Spain, using the shoring, clearing and striking (SCS) process. Loads on shores were recorded during the different construction stages of floor slabs 1 to 6. The two first floor slabs had geometry different than the rest. The experimental results were used to analyse load transmission between slabs and shores during the construction of the building with a SCS process. The experimental results were compared with those obtained applying simplified methods that consider the real stiffness of the shoring, obtaining that the method with a better fit was the New Simplified Procedure.
