In this type of floor, beams and slabs are designed as rectangular sections and the slabs are supported on beams. It is a monolithic construction both the beams and slabs are cast together. The beam used in monolithic construction is called a T-beam (i.e., a part of slab acts as a flange of the T-beam).
The main reinforcement of the slab runs parallel to the short span. However, some reinforcement is provided on the other, as in RCC slab floor, as distributors. In case of equal spans two-way slabs may be constructed with reinforcement provided on both directions. Sometimes the projecting beams are covered by providing a false ceiling underneath it (Fig. 23.9).

The construction procedure is same as that of RCC slab floor, except for the type of centring or formwork required for the floor.
