1.0 INTRODUCTION TO CASE STUDY Initially, we proposed a bungalow from one of our group member’s dad’s office, but eventually the first building did not fit the criteria as it is too small and has fewer columns and beams. After many times of brainstorming and searching for buildings that suit our requirement for building structure, we finally found a bungalow which is located in China. The total area of this bungalow is 389.36 m2. It consists of 1 master bedroom, 3 bedrooms, wet and dry kitchen, toilet, closet and car porch.

After notifying our tutor, Ms Ann, we did some modification, adding some beams and columns to evenly distribute among our 7 member so that each of us has 6 beams and 4 columns. The material for the wall is brick, the ceiling and floor is made out of concrete slab, the columns and beams also made up of concrete.

Slab H-G/3-5:

4.2/1.7 = 2.47 which is > 2, thus is one way slab

Slab G-F/2-5:

4.8/2.5 = 1.92 which is < 2, thus is two way slab
