Civil engineering design project technical report

First and foremost, the architectural drawings are important before starting the design process. From architectural drawings, structural drawings can be produced. The placement of column, beam and slab can be identified and evaluated whether it is suitable or not the placement of the structural member. After the placement is identified and evaluated, the size of each structural member can be calculated to make sure that each member can bear the load from the building. Firstly, for slab design, the thickness that has been chosen was 120 mm. The diameter bar proposed was 8 mm and grade concrete that has been chosen was 30 N /mm 2 . This was because since the slab that needs to be designed was big, it needs strong concrete. Since the grade concrete is strong already so the bar size chosen was 8 mm to reduce the cost as the smaller diameter of a bar the lower the price. The thickness of the slab can be considered as thin but from the calculation all of the checking pass and did not fail. Plus, the slab that needs to be designed was on the ground floor where there is no toilet, so a drop of 50 mm does not need to be considered. Next, for beam design, the size of the beam was 150 x 239 mm. The diameter of bar and link was 12 mm and 8 mm respectively. The size proposed was based on the biggest slab that was connected to the beam. The size proposed for bar and link was proposed based on the size of the beam. Based on the calculation, the size proposed, diameter bar and link proposed satisfy requirements for a beam. It can support the load from the slab, brick wall if any, and its self weight to be transported to the column. Other than that, for column design, the size proposed was 300 x 450 mm, the diameter of bar and link was 25 mm and l O mm. The size of column proposed was based on the value of axial loading from roof that the column needs to support. The bar size and link diameter proposed was based on the size of column. From the calculation, the size proposed passed the requirement which was the column must be a short and biaxial column. The column must need to be categorized as short column because the deflection was small and more suitable as the building that needs to be design was only a double story house.
