Prefabricated prestressed sandwich floors
Reducing the material consumption of flat floor slabs
Over the years, the development of reinforced-concrete floors for multi-story building construction has given rise to a large number of different designs. When reinforced-concrete construction was still in its infancy, the main aim was to minimize material consumption. This is why floors for building construction were designed as distributed-support structures composed of primary and secondary floor beams (see F. Hennebique 1895). In the following period, efforts were mainly geared towards reducing labor costs, which is why the use of flat floors became more widespread (see R. Maillart).
