Function |
Sub-Parts |
Types |
Foundation |
The lowest part of the building structure, set in the ground. |
Provides stability, distributes the load to the soil, and prevents settling. |
Footings, Piles, Grade Beams |
Shallow (e.g., spread footing), Deep (e.g., pile) |
Plinth |
The part of the structure between the ground level and the floor level of the building. |
Raises the floor above ground level to prevent moisture and insect entry. |
Plinth Beam, Plinth Protection Layer |
- |
Columns |
Vertical structural elements that support beams and floors. |
Transfer the weight of the structure from above floors to the foundation. |
Reinforcement Bars, Column Casing |
T-shaped, L-shaped, Circular, Rectangular |
Walls |
Vertical enclosures made of materials like bricks, concrete, or wood. |
Provide structural support, enclose spaces, and offer security, privacy, and insulation. |
Inner Wall, Outer Wall, Partition Wall |
Load-bearing, Non-load-bearing, Shear Wall |
Beams |
Horizontal structural members spanning between columns. |
Distribute loads from floors, ceilings, and roofs to columns. |
Reinforcement, Stirrup, Concrete Cover |
T-beam, L-beam, I-beam, Continuous Beam |
Floors |
Horizontal surfaces in a building used as walkable surfaces. |
Support the weight of occupants and objects; separate building levels. |
