Abstract [en]

The paper focuses on the finite element modelling of a floor slab made of prefabricated hollow core floor units. The subject of the numerical analysis is a floor that has been investigated experimentally in VTT, Finland. The DIANA finite element analysis software has been used. Internal forces and displacements, as well as a failure load obtained from the finite element model, are compared with selected provisions given in the literature. The numerical analysis confirmed the inconsistencies and unreliability of existing models mentioned in the authors’ previous papers. The modelling technique presented in the paper, which takes into account the possibility of cracking of longitudinal joints between prefabricated units, provided reliable results consistent with experimental results.
