3. 1. Introductionto Project
In this project, we are required to form a group of 3 and design a double
storey bangalow from a provided set of plans. Then, we are to identify and
analyse the beams and columns in the bangalow. After designing a bangalow
with varying beam and column arrangement, we are required to produce a
structural plan drawing for each floor for further analysis.
With the information of the structural plan drawings, we have to proceed with
calculating and identifying the slab system and load distribution for the beams
and columns. Each of us is required to calculate minimum of 6 beams and 3
column from both ground and first floor. Formula used are as follow.
Slab System
Ly/Lx>2(one way slab system)
Ly/Lx<2(two way slab system)
Beam Calculation
Beam self-weight =beam size x density if reinforced concrete
Slab dead load =thickness x density of reinforced concrete x Lx/2(trapezoid)
=Thickness x density of reinforced concrete x Lx/2 x 2/3(triangular)
Slab live load = live load (UBBL) x Lx/2(trapezoid)
=live load (UBBL) x Lx/2 x 2/3(triangular)
Brickwall dead load = wall height x thickness x density of bricks
Column calculation
Beam self-weight = beam size x density of reinforced concrete x length
Size of dead load = thickness x density of reinforced concrete x tributary area
Slab live load = live load(UBBL) x tributary area
Brick wall self-weight = thickness x wall height x density of bricks x length
Column self-weight = width x length x height x density of reinforced concrete
4. Specifications
UBBL
Density of reinforced concrete = 24kN/m³
Density of bricks = 19kN/m³

25. 7. Conclusion
From this project, we learnt the proper method of calculation and application
for the analysis of load distribution to a building structure. The analysis on the
structural system has helped us to a better understanding on the design of a
basic structure in a building. The calculation exercises also enable us to
practice a proper measure of load distribution in a structural system. Upon
completion, we are able to gain basic knowledge about the formulas of load
distributions.
