Structure

In construction, the structure refers to the framework or skeleton of a building or infrastructure that supports and transfers loads safely to the ground. It is the core component that ensures the building remains stable, safe, and durable.

Types of Structures in Construction:

1. Load-Bearing Structure

  • Walls carry the load of the entire building

  • Common in small-scale or traditional buildings

2. Framed Structure

  • A system of beams and columns supports the load

  • Widely used in high-rise and commercial buildings

  • Examples: RCC (Reinforced Cement Concrete) frame, Steel frame

Main Structural Components:

a. Foundation

  • Transfers the load from the structure to the ground

  • Types: Shallow (spread footing, raft), Deep (pile, caisson)

b. Columns

  • Vertical members that carry compressive loads

  • Transfer load from slabs/beams to foundations

c. Beams

  • Horizontal members that carry loads from slabs and transfer to columns

  • May be RCC, steel, or prestressed concrete

d. Slabs

  • Flat horizontal elements forming floors and ceilings

  • Transfer load to the supporting beams or walls

e. Walls (in some designs)

  • May be structural (load-bearing) or non-structural (partition)

f. Roof

  • Covers and protects the structure

  • Can be flat, pitched, or domed, depending on function and climate

g. Staircases & Ramps

  • Provide vertical circulation between floors

Structural Design Process:

  • Analysis of Loads and Soil Reports

  • Structural Layout Planning

  • Design Calculations using software (like STAAD, ETABS)

  • Preparation of Structural Drawings

  • Reinforcement Detailing (Bar Bending Schedule)

  • Supervision During Construction
