1. Introduction to 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 SystemLy/Lx>2(one way slab system)Ly/Lx<2(two way slab system)

Beam CalculationBeam self-weight =beam size x density if reinforced concreteSlab 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 calculationBeam self-weight = beam size x density of reinforced concrete x lengthSize of dead load = thickness x density of reinforced concrete x tributary areaSlab live load = live load(UBBL) x tributary areaBrick wall self-weight = thickness x wall height x density of bricks x lengthColumn self-weight = width x length x height x density of reinforced concrete

Specifications

UBBL Density of reinforced concrete = 24kN/m³Density of bricks = 19kN/m³

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.
