A presentation that briefly goes through the introduction and construction steps of Beam, Column, and Slabs

1. Ahsanullah University of Science and Technology
Department of Civil Engineering
Course No : CE 200
Course Title : Details of Construction

2. Column
Beam &
Slab

3. Load Transfer Mechanism
Slab Beam Column Foundation Soil

4. COLUMN
A column or pillar is a structural element that transmits the weight of the
structure above to other structural elements below.
A Compression member
Carries Axial Loads
Can sustain the structure under seismic conditions

5. Construction Steps
Step-1 •Reinforcement Placing
Step-2 •Formwork
Step-3 •Concrete Casting
Step-4 •Compaction
Step-5 •Removal of Formwork
Step-6 •Curing

6. Reinforcement Placing
Kicker Overlapping/Splicing

7. Reinforcement Placing
Placing of Tie Bars
Hooks

8. Reinforcement Placing
Column with Complete Reinforcement

9. Formwork
Timber Formwork
Steel Formwork

10. Formwork
After Completing Formwork
Centering of the Formwork

11. Concrete Casting

12. Compaction

13. Removal of Formwork

14. Curing

15. BEAM
Beams are horizontal structural element.
Primarily carry vertical gravitational forces
Also carry horizontal loads(due to earthquake or wind)

16. Construction Steps
Step 1
•Formwork
Step 2
•Reinforcement
Step 3
•Concrete Casting & Compaction
Step 4
•Curing

17. Formwork
Timber Formwork
Steel Formwork

18. Reinforcement Placing
Stirrups spacing & Clear cover

19. Reinforcement Placing
Hooks Beam Column Joint

20. Reinforcement Placing

Reinforcement
Details

21. Concrete Casting & Compaction
From two different sites

22. Curing

23. Completed Slab

24. SLAB
Used to create flat horizontal surfaces such as floors, roof decks and ceilings
Generally several inches thick about 100-500mm
Supported by beams,columns, walls, or the ground.

25. Construction Steps
1
• Formwork Preparation
2
• Reinfircement Placing
3
• Concrete Casting
4
• Curing
5
• Removal of Formwork

26. Form Work
Steel Formwork Wooden Formwork

27. Props

Braces

28. Reinforcement in Slab
• Slab Reinforcement includes straight & cranked bars
• Extra tops near supports or negative moments

29. Clear Cover
• CC Blocks made at site
• 3” CC Blocks used on tops and 1.5” on bottom bars
3” cc block
1.5” CC block

30. Casting
• Whole process completed within the same day of starting

31. Compaction
• Compaction done using vibrator machine
• Surface smoothened using flat wooden plank

32. Curing & Fromwork Removal
• Curing using ponding Method
• Cured for 3 weeks then formwork is removed

33. Whole process via Animation
