2. • Introduction
• Advantages of steel building construction
• Disadvantages of steel building construction
• Main uses of steel building
• Site investigation, fabrication and key building
elements of steel building
• Cost details of the construction
• Suitability of steel building construction to Sri
Lanka

3. • Steel plays a central role in many of the most
sophisticated and accomplished examples of modern
building design.
• Steel can either be used for the inner support structure
or outer covering.
• Structural steel frameworks are assembled onsite (The
processes involve lifting and placing components into position,
then connecting them together)

4. • Consistent Material Quality
• Light weight and strong
• Non-Combustible Material
• Dimensionally Stable in any Climate

5. • Insect Resistance and steel will not Rot
• Can build very tall and wide (tallest buildings
in the world)
• Prefabricated – frames assemble quickly

6. • Steel is an expensive material (much more
expensive than masonry or concrete)
• Frames are unstable
• Needs fire protection
• Needs separate “skin”

7. • Steel Building used as storage buildings
• Steel Buildings as Skyscrapers
• Steel Buildings used as Office Buildings and
Commercial Buildings.
• Steel Buildings used as Temporary Buildings

Main Uses of
Steel Building

9. • Minimum repair and maintenance
• Durable
• Speed of construction
• Building are movable through deconstruction or
mobility.

10. • Strong internal framework.
• Speed of construction
• Ease of installation
• Design Flexibility

11. • Strength & Stability
• Speed of Construction
• Comparatively less human resources in
installation.
• Design Flexibility

12. • Ease of Deconstruction
• Re-usability of steel
• Speed of construction
• Stability
• Durability

13. The main purposes of site investigation
• To determine the nature of the sub soil
• To determine the bearing capacity of the
building.
• To determine the possibility of the ground
movement.

14. Fabrication describes the processing of
steel from manufacturer to final delivery
to a construction project, which includes;
–Coating
–Stockyard storage
–Cutting
–Bending
–Welding

15. Technology used for columns
1. Top beam
2. Side plate
3. Packing plate
4. Bottom beam
5. Bottom plate
6. Angle

16. • Used Arched welding
Prepare the edge to get
strength
• Stiffener plate welded
Get more strength
Prevent curving beams

17. • Using studs for beam
• Used sink pose pate for steel
• Removed corrosion
Using sand
Using machine (grinder)

18. Planning for Construction
• Cost
• Program
• Quality

19. • Establishing suitable and safety foundation
• Lifting and placing components into position
• Aligning the structure

21. Metal deck may need to be assessed for its ability
to stabilise the steel members

23. • Total cost for the whole construction project is
Rs.48580000/=
• Beams and Columns are separated and
identified by their sizes
