• ERASE is used to erase the unwanted lines which cannot be trimmed using Trim Command

Ground Floor Plan

First Floor Plan

The structural drawing required to be submitted on the site for construction are:

• Center line Drawing
• Footing and column layout with reinforcement details
• Column schedules with reinforcement details
• Plint beam with reinforcement details
• First floor beam with reinforcement details
• First floor slab layout with reinforcement details

The Center line Diagram with the columns placed

The Assumed Column size for the Building are:

• 9"x12"
• 4.5"x4.5"

The Assumed Beam Size for the Building are:

• 9"x9"

The Assumed thickness of the Slab are:

• 125mm

Calculation of Dead Load

Column Deadload

Dead load of the column is calculated by multiplying the size of column into height (indirectly its the volume of the column) and then multiplying it with the unit weight of concrete

where

9" = 228.6mm

12" = 304.8mm

Column size (Volume) = 0.2286mx0.3048mx4.5m

Unit weight of concrete = 25 kN/m³

Dead load = 0.2286x0.3048x4.5x25

= 7.84 kN

where

4.5" = 114.3mm

Column size (Volume) = 0.1143mx0.1143mx4.5m

Unit weight of concrete = 25 kN/m³

Dead load = 0.1143x0.1143x4.5x25

= 1.470 kN

Beam Deadload

Dead load of the Beam is calculated by multiplying the size of beam into length (indirectly its the volume of the column) and then multiplying it with the unit weight of concrete

Assuming the length of the beam as 1m( usually Dead load for beams are calculated for unit length and then multiplied with the actual length)

Where

9" = 228.6mm

Beam size (Volume) = 0.2286mx0.2286mx1m

Unit weight of concrete = 25 kN/m³

Dead load = 0.2286x0.2286x1x25

= 1.31 kN

Slab Deadload

Dead load of the Slab is calculated by multiplying the lenght and width of slab into thickness (indirectly its the volume of the slab) and then multiplying it with the unit weight of concrete

The UDL for all rooms(Living Room, Guest Room, Kitchen, Dinning room, Utility, Toilet and Bathroom) = 2 kN/m²

Slab size (Volume) = 1mx1mx0.125m

Unit weight of concrete = 25 kN/m³

Dead load = 1x1x0.125x25

= 3.125 kN/m

The UDL for Balcony, Car parking and Staircase = 3 kN/m²

Slab size (Volume) = 1mx0.125mx1m

Unit weight of concrete = 25 kN/m³

Dead load = 1x1x3x0.125x25

= 9.375 kN/m

Wall Deadload

Dead load of the Wall is calculated by multiplying the thickness of wall into height of the wall and then multiplying it with the unit weight of Brick wall

Assuming the thickness of the wall as 230mm

Height of the Wall = 4.5m

Unit weight of Brick Wall = 20 kN/m²

Dead load = 0.23x4.5x20

= 20.7 kN/m

Result:
