  1. Stresses Found In Structural Members

  2. Forces Acting Simply Supported Beam Bending

  3. Bending Load Load Applied A Beam will want to Bend Support Wall Below A

  4. Bending Load Load A We would prefer if it did this Support Wall Below A

  5. Tension Induced Load Load A Support Wall Below A

  6. Tension Induced Load Load A Tension If is does what we want Support Wall Below A

  7. Counteract Tension Load Load A Reinforcement to counteract Tension Support Wall Below A

  8. Counteract Tension Load Load Load Reo for crack control Effective Depth Tension Reinforcement as low as possible Support Wall Below

  9. Forces Acting Simply Supported Beam Compression

  10. Compression Induced to Top of Beam Load Load A Compression Usually the Concrete can Withstand without Reo Tension Support Wall Below A

  11. Compression Acting at Supports Load Load Load Reo for crack control Effective Depth Tension Reinforcement as low as possible Support Wall Below

  12. Compression Acting at Supports Load For high compression reo will prevent surcharge Load Load Reo for crack control Effective Depth Tension Reinforcement as low as possible Support Wall Below

  13. Compression Acting at Supports Load Load A Support Wall Below A

  14. Compression Acting at Supports Load Wall Below Section A-A

  15. Compression Acting at Supports Load Wall Below

  16. Compression Acting at Supports Load Beam compressed against support by load Wall Below

  17. Compression Acting at Supports Load Stirrups placed to prevent bursting Wall Below

  18. Compression Acting at Supports Load Load Load Stirrups closely spaced to prevent bursting Support Wall Below

  19. Compression Acting at Supports Load Load Load Stirrups spaced further apart as no compressive force Support Wall Below

  20. Compression Acting at Supports Load Load Load Stirrups required to support top steel – FRAMING BARS Support Wall Below

  21. Forces Acting Simply Supported Beam Shear

  22. Shear Acting On Simply Supported Beam Load Load A Support Wall Below A

  23. What is Shear? Shear

  24. 2 Types of Shear Forces • Vertical Shear • Horizontal Shear

  25. Shear Forces • Vertical Shear

  26. Shear Forces Load Load Load Support Walls Below resist downward force

  27. Shear Forces Load Load Load No Resistance where there is no support

  28. Shear Forces Load Load Load Beam will shear at support

  29. Shear Forces Load Load Load A B A B Reinforcement at supports to resist shear Stirrups omitted for clarity

  30. Shear Forces Load Load Load Support Walls Below resist downward force

  31. Shear Forces • Horizontal Shear & Diagonal Shear

  32. Horizontal Shear Load Load Load Reinforcement to Prevent Horizontal Shear if requiered Support Wall Below

  33. When 2 Types of Shear Forces Meet • Diagonal Tension Cracking

  34. Diagonal Shear Load Load Load Stirrups Prevent Diagonal Shear Support Wall Below

  35. Multi Span Beam

  36. Load on Continuous span Bean Load Load Support Walls Below

  37. Load on Continuous span Bean Load Load Support Walls Below

  38. Load on Continuous span Bean Load Load Tension Tension Tension

  39. Forces that act on Beams Load Load Bending Compression Compression Compression Bending Bending Shear Shear Shear Shear

  40. Contra flexure Point of Maximum Bending Point of Maximum Bending Point of Maximum Bending

  41. Contra flexure Bending Reduces Bending Reduces Bending Reduces

  42. Contra flexure ZERO Bending ZERO Bending ZERO Bending

  43. Fixed End Beam

  44. Load on Continuous span Bean Load Load Fixed Connection Support Walls Below

  45. Load on Continuous span Bean Load Load Tension Tension Fixed Connection Tension Tension Support Walls Below

  46. Compression Acting at Supports Load Load Support Walls Below

  47. Compression Acting at Supports Load Load Support Walls Below

  48. Fixed End Beams Load Load Load Point of Contra flexure Support Walls Below

  49. Forces that act on Beams Load Load Fixed or Restrained End Bending Bending Compression Compression Compression Bending Bending Shear Shear Shear Shear
