Flat Slabs

The flat 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.

Flat Slab Support Methods

The flat slabs may be supported by three methods:

1. Using a drop panel and a column capital in flat slab
2. Using a drop panel without a column capital in flat slab
3. Using a column capital without drop panel in flat slab

Drop Panel

The thickened part of a flat slab over its supporting column is technically known as a drop panel as can be observed in the figure below

Uses of Drop Panels

What are the Uses of Drop Panels?

Answer for Uses of Drop Panels is provided below

1. Drop panels increase the shear strength of the flat slab floor (i.e it resists shear).
2. Drop panels increase the flat slab's negative moment capacity.
3. Drop panels reduce deflection by stiffening the flat slabs.
