BRIEF INTRODUCTION
This is a 2 storey bungalow situated on a plot of land consisting
entertainment area, neat lawn while located in a hot area. This house size of
this house is large which fits perfect for a family. A living room is located at
the first floor for the leisure purposes. This gives users a sense of privacy.
The pitch roof adds a little extra space by allowing for an attic area in this
beautiful compact home.

DESIGN BRIEF
Dead Loads of Structure (Constant)
Dead load factor = 1.4 (According to UBBL)
1.Density of Materials
a)Reinforced Concrete: 24kN/m3
b)Brick Masonry: 19kN/m3
c)Roof Slab :1.0kN/m2
2.Reinforced Concrete Beam Self Weight
Cross-sectional area
= width x height of the beam
= 0.2m x 0.3m = 0.06m2
Beam self-weight per meter length
3. Brick wall self-weight
= thickness x height x density of brick wall
= 0.15m x 3.0 x 19kN/m2
= 8.55 kN/m
4. Floor slab self-weight
Floor slab self-weight per meter square
= slab thickness x density of concrete
= 0.15m x 24 kN/m3 = 3.6 kN/m2

ROOM Live Load per meter square area (kN/m2)
Bedroom 1.5
Dining Area 2.0
Living Area 2.0
Bathroom 2.0
Kitchen 3.0
Corridor 2.0
Storage 4.0
Roof 0.5
Live loads of Rooms according ot its function (Constant)
Live load factor 1.6
Column design (Capacity of Column)
Given, Fcu = 30 N/mm2
Fy = 460 N/mm2
Ac = 200mm x 200mm
= 40000mm2
Assuming 2% Steel reinforced into concrete
Asc = 2% x 40000 mm2
= 800mm2
N = (0.4 x Ac x Fcu) + (0.8 x Asc x Fy)
= (0.4 x 30 x 40000) + (0.8 x 460 x 800)
= 774.4 kN

CALCULATION FORMULA
1.Slab System
Ly = Longer side of slab Lx = Shorter side of slab
When Ly/Lx > 2 (One way slab system) When Ly/Lx < 2 (Two way slab system)
2.Column Calculations
a)Dead Load
Brick Wall Self Weight = [Material Density x Thickness x Height] x [Total length of wall in
Tributary Area]
Slab Self Weight = [Material Density x Thickness] x [Area of Tributary Area]
Beam Self Weight = [Material Density x Size of Beam] x [Total Length of Beam in
Tributary
Area]
Column Self Weight = Material Density x Size of Beam x Height of Column
b)Live Load
Live Load on Slab = Live Load (UBBL) x Area of Space within Tributary Area
c)Ultimate Load
Ultimate Load = (Total Dead Load x 1.4) + (Total Live Load x 1.6)
3.Beam Calculations
a)Dead Load
Beam Self Weight = Material Density x Size of Beam
Brick Wall Self Weight = Material Density x Thickness x Height
Dead Load on Slab (One Way Slab) = Material Density x Thickness x (Lx/2)
b)Live Load
Live Load on Slab (One Way Slab) = Live Load (UBBL) x (Lx/2)
Live Load on Slab (Two Way Slab)
(Triangular) = Live Load (UBBL) x (Lx/2) x %
(Trapezoidal) = Live Load (UBBL) x (Lx/2)
c)Ultimate Load
Ultimate Load = (Total Dead Load x 1.4) + (Total Live Load x 1.6)
