            PROCEDURE:

            STEPS FOR PLAN:

• Open auto cad and enter UN(units command) in the command box and select type as decimal and set precision of decimal as 0.
• Select X line command and draw horizontal line and vertical line.
• Trim the unwanted lines.
• Now select offset command and give an offset of 250mm to both horizontal and vertical line drawn by X line.
• Give the offsets as follows in the X direction.
• Offset 3100 for bedroom.
• Offset 115 for internal wall.
• Offset 2250 for kitchen/drawing room/ dining room.
• Offset 115 for internal wall.
• Offset 1250 for both toilet.
• Offset 230 for external wall.
• Give the offsets as follows in the X direction.
• Offset 3100 for bedroom.
• Offset 115 for internal wall.
• Offset 3225 for bedroom.
• Offset 230 for wall on both sides of stars.
• Offset 230 for treads.
• Offset 1200 for landing of staircase.
• Offset 2400 for width of staircase.
• Offset 2250 for kitchen dining bedroom.
• Offset 1000 for veranda.

     LEGENDS OF WINDOW:

     SIZE OF WINDOWS ASSUMED:

• W1= 1000 X 1200
• W2=900X1200
• W=1200X1200

   LEGENDS OF DOOR:

   SIZE OF DOORS ASSUMED:

• D=1200 X 2100
• D1=1000 X 2100
• D2= 900 X 2100

• Windows and doors are drawn by using line command.
• Section lines are drawing by using layer and changing the layer type.
• Hatch- For hatching the columns type hatch in command box – open settings- select pattern – select pattern as AIR-CONC – select global scale factor as 0.7
• Dimension – For drawing dimension using dimension tool in the ribbon.
• Text – for naming of plan use text in ribbon in that use multiline text and keep the height of text as 200.

    STEPS FOR DRAWING SECTION AA-

• Select x line command and external the lines from the plan in the downward manner to create projections.
• Offset 150mm from the ground level.
• Offset 3100 for ground floor.
• Offset 3100 for second floor.
• Offset 3100 for third floor.
• Offset 1000 for parapet wall.
• Offset 2500 from terrace level.
• Offset 450 from mumty for parapet wall of mumty.
• Offset 600 and offset 1200 for O.T.H
• For drawing of staircase offset 1250 for tread and offset 150 for rise of staircase.
• Offset 115 below floor level for slab.
• Draw the chajjas and windows as per the sizes considered and standards.
• Draw the railing of staircase in dash manner from the layers and change the layer to ACADISO03W100.
• Dimensions by dim linear or dim continue command.
• Select the multiline text for naming of the section.

 STEPS FOR DRAWING SECTION BB-

• Rotate the entre plan drawn earlier in the 90 degrees direction o draw the section BB.
• Select x line command and take the projectors of the rotated plan in the downward manner.
• Take the projections of all internal walls of 115 mm and external walls of 230 mm.
• Draw a base line to draw the section BB.
• Offset 150 from base line.
• Offset 2450 for ground floor.
• Offset 2850 for first floor.
• Offset 2850 for second floor.
• Offset 2850 for third floor.
• Offset 1000 for parapet wall.
• Thickness of slab is assumed to be 125mm.
• Offset 125 room each floor in downward manner.
• Dimensions – Use dim linear or dim continuous for giving the dimensions.
• Draw the windows as desired by using the line command.

1. Calculate the self- weight of these Columns and Beams:
   C1 (230 x 230) :

Let’s take a column of size C1 (230x230)

Assume height =1m

Self weight of column C1 is,

Total volume of concrete = 0.23x0.23x1

=0.053KN/m3

Unit weight of concrete = 25KN/m3

Self weight of column = 25 x 0.053

                                 =1.33 KN

C2 (R-150MM)  :

Let’s take a column of size C2 150MM

Assume height =1m

Self weight of column C2 is,

Total volume of concrete = 3.14X(0.15)² X1

=0.07KN/m3

Unit weight of concrete = 25KN/m3

Self weight of column = 25 x 0.07

                                 =1.77 KN

2. 
   Calculate the wall load on a beam of height 3.1M?

Let’s calculate the wall load for a height 3.1 m

-Height of the wall = 3.1m

- Thk.of the wall = 230mm

- Unit.wt of brickwall = 20KN/m3

- Dead load of wall = 20 x3.1 x0.23

                             =14.3KN/m

TOTAL LENGTH OF WALL = 69.5m

                                                =14.3x69.5

                                                =991.1KN

3. 
   Calculate the self-weight of a slab of 150mm thickness and span 18.3m x 6.1m?

Self – weight of column is,

Total volume of concrete

                             =18.3 x6.1x0.15

=16.75KN/m3

Unit weight of concrete= 25KN/m3

Self weight of slab = 25x 16.75

                             = 418.6KN
