Lesson 21 : Upper Floors

Beam-Slab Flooring

When the width of room becomes more, the span of slab increases, and simple R.C.C. slab becomes uneconomical. In that case, the floor structure consists of R.C.C. beams and slabs cast monolithically. The beams, known as T-beams, act as intermediate supports to the slab which is continuous over these beams. When the size of the room is very large, these floor beams are supported on longitudinal beams which, in turn, are either supported on R.C.C. columns or end walls.
