  • Hi ,

    I have a similar issue where the beam gets extended beyond a column to around 6-7 ft. This beam starts from a column, gets another column support at around 4 feet and then gets extended and acts as a cantilever beam. At around 6 feet from the column end, there is another another beam coming perpendicularly and meeting this beam, which has no support of column at its end. Is this okay? Please advice as the structural engineer says this is okay.

Transcript

  • 1. CIVIL ENGINEERING
  • 2. SUPERSTRUCTURE
    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.
  • 3. Types.
    • Masonry
    BEAMS,COLUMNS AND LINTELS
  • BEAMS
    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.
  • 6. R.C.C. BEAMS
    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
  • 7. Load Acting on a Structure
    • Dead Load
    Dead load is the self-weight of thevarious components of a building.
    • Live Load
    Live load is the external superimposed load on a structure. Live loads may be
    Uniformly distributed load
    Uniformly varying load
    Concentrated load
  • 8. Types of BEAMS
    SIMPLY SUPPORTED BEAM
    FIXED BEAM
    CANTILEVER BEAM
    CONTINUOUS BEAM
    OVERHANGING BEAM
  • 9. Simply supported beam
    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).
  • 10. Fixed beam
    In this beam, both ends of the beam are rigidly fixed into the supports.Also, Main reinforcement bars and stirrups are provided.
  • 11. Cantilever beam
    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
  • 12. Continuous beam
    It is supported on more than two supports . This beam is more economical for any span lengths.
  • 13. Overhanging beam
    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.
  • 14. R.C.C. Beams
    • Singly Reinforced Beam
    • 15. Doubly Reinforced Beam
  • Types of Loading on Beams
    • Concentrated Load
    • 16. Uniformly Distributed Loads
    • 17. Uniformly Varying Loads
    • 18. Arbitrary Loading
  • 19. COLUMNS
    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.
  • 20. Types of Columns
    • Long Column Or Slender
    • 21. Short Column
    • 22. Intermediate Column
  • R.C.C. Columns
    Columns of square, rectangular and circular sections
  • 23. Précautions of Columns construction
    • Process of construction
    • 24. Vertical Height of concrete
    • 25. Columns for more then one storey
    • 26. Load on the column of the top storey
  • Steel Columns or Stanchions
    • Standard Structural Steel Sections
    • Build-up Column Sections
  • LINTELS
    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.
  • 27. CLASSIFICATIONOF LINTELS
  • R.C.C. Lintel Over Inteior Door Opening
  • 32. Effective Load On Lintel
