The slab table is supported by four slab props. The stiffnesses of the props were represented by BEAM elements with a corresponding cross-section, which were fixed at the free end. The simulation showed a stress concentration in the area of the floor prop connection (see Figure 2). However, the calculated stresses are within the allowable range, thus demonstrating the structural integrity of the slab table.
The real deflection of the slab table was determined with a 3D measurement of concreted slabs. The deflection calculated in the FEM simulation showed good agreement with the measured values (deviation measurement to simulation ≈ 5%).
