3. 1.0 Introduction to case study
The case study we chose is a two and half storey bungalow. It is located in Jade Hill,
Kajang. It is designed by Arkitek Juruperunding Suria Rahim Sdn. Bhd.
The built up area of a single unit of the bungalow is approximately 4400 sq. ft. Col-
umns and beams are assembled in moment resisting frames which is a common prac-
tice in residential design, in order to define the location of each columns in the build-
ing, we have studied and analyzed the spaces through plans.

22. 7.0 Conclusion
Throughout this project, we learnt about structural theory and basic structural pro-
posal. We learnt about the load path in slab ( one way and two way slabs). We are
now understand the concept of structural analysis which needed to identify the
structural components.
We learnt how load is sitting on beams on columns. By calculating load transferred
to beams and loads, we clearly understand the basic requirement such as thickness
needed for a column or beam while designing a building. This is helpful as it is
important for us in our future study.
