The prestressed concrete roof slab lightened by polystyrene blocks

Companies Trenon and Bestr carried out an interesting construction project. They have designed a prestressed waffle slab structure into the false formwork of polystyrene blocks.

The structure was cast on the original ceiling serving as formwork, which was supported by temporary props. Roof slab was prestressed after 28 days since casting. Since this time, the new roof slab has acted independently on the original one and is able to carry out another permanent and variable loads.

IDEA StatiCa and MIDAS civil together?

MIDAS Civil and IDEA StatiCa offer a complex solution for the design and checks of the structures.  MIDAS Civil as a tool focused mainly on bridge engineering has guaranteed the design with the option of time-dependent analysis and the impact of the rheology and precisely captured the behavior during the construction. IDEA StatiCa has simplified the job, mainly the checks of the cross-sections in all construction stages.

Find out more about the project in one of our case studies.
