the prestressing of a concrete floor slab can eliminate its usual deflection below support level. this is achieved either by pre-tensioning, where precast floor units are used, or by post tensioning with steel wire tendons incorporated in an in-situ concrete slab. suspended floors can be constructed in three basic forms:-
suspended concrete floors. there are occasions where due to the ground conditions that a suspended floor is needed rather than a ground bearing slab. these include soil with a low bearing capacity, sloping sites, soils containing aggressive chemicals and those with high water levels marshall and worthing, 2000 .
