This document discusses different types of reinforced concrete structures including in situ concrete structures like landings, support beams, and spine beams for stairs. It also discusses flush slabs, which are two-way reinforced concrete slabs without beams or girders that directly transfer loads to supporting columns. Some benefits of flush slabs are flexibility in room layout, ease of framework installation, and reduced building height. However, flush slabs have medium span lengths and require higher slab thickness compared to typical reinforced concrete slab systems.

8. Flush slab
A flush slab is a two-way reinforced concrete slab that usually does not have
beams and girders, and the loads are transferred directly to the supporting
concrete columns.

9. • Flexibility in room layout.
1. Partition walls can be placed anywhere.
2. Offers a variety of room layout to the owner.
3. False ceiling can be omitted.
• Ease of Framework installation.
1. Big table framework can be used in flush slab
• building height can be reduced.
1. As no beam is used, floor height can be reduced and consequently the
building height will be reduced.
2. Approximately 10% in the vertical member could be saved
3. Foundation load will also reduce.

10. demerit of flush slab
• Span length is medium.
1. In flush slab system, it is not possible to have large span.
• Higher slab thickness
1. Compared to typical reinforced concrete two way slab system, the thickness
of flush slabs are higher.
