SLIDE 3: INTRODUCTION – WHAT IS A SLAB?


8.1 Introduction to Reinforced Concrete Slabs
Definition
A slab is a horizontal plate element that forms the floor and roof of a building.
Key Characteristics
• Horizontal orientation – provides flat surface for occupancy
• Plate action – transmits loads primarily through bending
• Two-way action – distributes loads in two directions (in most cases)
• Composite action – works together with supporting beams and
columns

Primary Functions

Function Description

Load
Carries dead loads (self-weight, finishes) and live loads (occupancy, furniture)
Support

Load
Transfers loads to supporting beams, columns, or walls
Transfer

Floor/Roof
Provides usable floor area or weather protection
Surface

Diaphragm
Resists lateral loads (wind, seismic) and distributes them to lateral load-resisting systems
Action



Key Concept: Slabs are one of the most fundamental structural elements
in building construction, serving both structural and functional purposes.
