Flat Plate Floor System
Flat Plate Floor System: The flat plate is simply a slab of constant thickness supported directly on columns or load bearing walls. This system is one of the most common structural system used in building construction due to the ease and speed of making the formwork (as there is a uniform thickness, one need a formwork with a flat soffit).
The span of a flat plate floor is governed by the both the strength requirements and serviceability requirements represented by the deflection. In order to be economic, try to limit the span in the range of 6 to 8 m for reinforced concrete flat plates.
- Covers medium spans (6-8 m)
- Lower lateral load capacity compared to solid slab system
- May need shear reinforcement at the columns to resist punching
- May not be suitable for heavy loads.
