Elevated Slab

Definition

A roof slab or floor supported by structural members.

Purpose

Elevated slabs are used in construction to create floors or roofs that are not directly supported by the ground but rather by beams, columns, or other structural elements. This allows for multiple levels within a building, providing additional space and functionality.

Examples of Use

• Constructing the floors of a multi-story office building.
• Creating the roof of a parking garage supported by columns and beams.
• Building a suspended concrete floor in a residential home with a basement.

Related Terms

• Slab-on-Grade: A concrete slab poured directly on the ground.
• Precast Slab: A concrete slab that is cast and cured in a location other than its final position.
• Beam: A horizontal structural element that supports the slab.

Notes

• Elevated slabs require careful design and reinforcement to ensure they can carry the expected loads.
• The construction of elevated slabs involves temporary formwork and shoring systems to support the concrete until it cures and gains strength.
