Civil Engineering (Beams,Columns)

  2. 2. SUPERSTRUCTURE<br />Superstructure of a building is the portion of the Structure above the foundation. It provides the necessary utility of the building with comfort, Structural safety, ventilation, etc. <br />
  3. 3. Types.<br /><ul><li>Masonry</li></ul>BEAMS,COLUMNS AND LINTELS<br /><ul><li>Roofing
  4. 4. Flooring
  5. 5. Plastering</li></li></ul><li>BEAMS<br />Beam is the horizontal member of a structure, carrying transverse loads. Beam is rectangular in cross-section. Beam carry the Floor slab or the roof slab. Bram transfer all the loads including its self-weight to the columns or walls.<br />
  6. 6. R.C.C. BEAMS<br />R.C.C. Beam is subjected to bending moments and shear. Due to the vertical external load , bending compresses the top fibers of the beam and elongates the bottom fibers. The strength of R.C.C. beam depends on the compsite action of concrete and steels<br />
  7. 7. Load Acting on a Structure<br /><ul><li>Dead Load</li></ul>Dead load is the self-weight of thevarious components of a building.<br /><ul><li>Live Load</li></ul>Live load is the external superimposed load on a structure. Live loads may be <br />Uniformly distributed load<br />Uniformly varying load<br /> Concentrated load<br />
  9. 9. Simply supported beam<br /> It is a beam supported freely at the two ends on walls or columns. In actual practice, no beam rests freely on the supports (walls or columns). <br />
  10. 10. Fixed beam<br /> In this beam, both ends of the beam are rigidly fixed into the supports.Also, Main reinforcement bars and stirrups are provided. <br />
  11. 11. Cantilever beam<br /> It is fixed in a wall or column at one end and the other end is free, it is called cantilever beam. It has tension zone in the top side and compression zone in the bottom side<br />
  12. 12. Continuous beam<br /> It is supported on more than two supports . This beam is more economical for any span lengths.<br />
  13. 13. Overhanging beam<br /> In overhanging beam, Its end extends beyond the wall or column support. Overhanging of the beam is the unsupported portion of the beam. It may be one side or both the sides of the support.<br />
  14. 14. R.C.C. Beams<br /><ul><li>Singly Reinforced Beam
  15. 15. Doubly Reinforced Beam</li></li></ul><li>Types of Loading on Beams<br /><ul><li>Concentrated Load
  16. 16. Uniformly Distributed Loads
  17. 17. Uniformly Varying Loads
  18. 18. Arbitrary Loading</li></li></ul><li>
  19. 19. COLUMNS<br />Column is a vertical structural member. It transmits the load from ceiling/roof slab and beam, including its self-weight to the foundation. Columns may be subjected to a pure compressive load. R.C.C. columns are the most widely used now-a-days.<br />
  20. 20. Types of Columns<br /><ul><li>Long Column Or Slender
  21. 21. Short Column
  22. 22. Intermediate Column</li></li></ul><li>R.C.C. Columns<br />Columns of square, rectangular and circular sections<br />
  23. 23. Précautions of Columns construction<br /><ul><li>Process of construction
  24. 24. Vertical Height of concrete
  25. 25. Columns for more then one storey
  26. 26. Load on the column of the top storey</li></li></ul><li>Steel Columns or Stanchions<br /><ul><li>Standard Structural Steel Sections</li></li></ul><li><ul><li>Build-up Column Sections</li></li></ul><li>LINTELS<br /> Lintel is a short beam with its ends built into a wall. It is a horizontal structural member placed over small openings of the wall for door, window, ventilator, cupboard, etc.<br />
  27. 27. CLASSIFICATIONOF LINTELS<br /><ul><li>Timber Lintel
  28. 28. Stone Lintel
  29. 29. Brick Lintels
  30. 30. Steel Lintels
  31. 31. R.C.C. Lintels</li></li></ul><li>R.C.C. Lintel Over Inteior Door Opening<br />
  32. 32. Effective Load On Lintel<br />
