This paper provides a procedure for finite element analysis of hollow-core slab floors, which may be necessary in case of large floor openings. Formulas for homogenisation of the floor properties are presented. Finite element modelling is discussed. Formulas for stress recovery are presented. As an example a floor is analysed with a 3 x 3.6 m opening.

Key words: Hollow-core slabs, trimmer, homogenisation, stress recovery, analysis procedure
