To Draw 2D Diagram Cross Section of Beam and Slab for the Given Data

Jun 25 2023


Doubly reinforced Beam

Aim

To draw simple 2D diagram representing the cross section of beam and slab for the given data.

Data:Draw the L/S and C/S of a doubly reinforced beam for a building having following details

  1. Clear span length = 5000 mm
  2. Bearing thickness = 300 mm
  3. Overall depth of the beam = 650 mm
  4. Breadth of the beam =300 mm
  5. Main reinforcement of beam (top) = #4-16mm dia bars
  6. Main reinforcement of beam (bottom) = #4-20mm dia bars
  7. Shear reinforcement of steel = 8mm dia bars @ 300mm c/c spacing

    8. Software used: Autocad

    Commands used:Limits, ortho, offset, line, zoom, array, donut, move, trim, extend, hatch, dimension, text etc.

    Procedure:

      The limits are set before starting the drawing. The lower left corner is set as default (0.0000, 0.0000). The upper right corner is changed as per our requirements.
  8. By using units command, we set the types as decimal, precision as 0.0000 and units to scale as millimetres.
  9. Ortho is switched off as the drawing requires use of inclined line also along with horizontal and vertical lines.
  10. By using the line command, the outline of the required drawing is drawn.
  11. By using the trim command, the extra lines are trimmed.
  12. Lines are extended using extend command wherever necessary.
  13. Donut option is used to represent the c/s of reinforcements.
  14. Offset command is used to get lines at regular distance.
  15. Hatching is done using hatch command.
  16. Dimensions are provided and text command is also used for labelling the drawing.

    17. Result:The required C/S of lintel and chajja is drafted using the software.
