Reinforced concrete building design project: project based learning (case study) / Ahmad Aqhram Shaiful Kharidan

The design works are done on six different structures. Those structures are very essential to the construction of the building. The most critical part of the structure is taken from the design key-plan in order to design the structure with the most suitable dimensions and reinforcements. Therefore, the procedure of the key-plan is crucial in the process of constructing a building. In this case, the construction of a two-storey building is started with the proposal of the project schedule. The project schedule plays a major role on keeping the work process smooth and avoiding any unwanted casualties. The project schedule also helps on reducing the construction period of the building. After the project schedule is finished, the Structural key-plan of the building will take place to acknowledge and determine the positions of the structures in each floor. The first structure is the slab with the largest area from the key-plan. A two-way restrained slab is analysed to determine the suitable and the most efficient type of reinforcement bars to be used. But first, the permanent load is determined by assuming the thickness of the slab. In this project, the thickness of the slab is 140 mm. The critical moment and the critical shear at midspan and support will also be determined by referring to the design appendix. It is crucial to determine the area or reinforcement bars because an area that is too small or too large can cause major failures on the structure. In this project, the type of reinforcements bar used for the slab structure is H8300 which means the diameter of the bar used will be 8 mm. The second structure that will be designed is the simply supported beam and the continuous beam. For simply supported beam, there is only one span of beam that will be analysed and design. The size estimated for the beam in this project is 450 mm in height and 200 mm in width. The design load of the beam will then be determined to obtain the moment and shear value. After that, the main reinforcements, and the shear reinforcements of the simply supported beam will be determined by referring to the design appendix. As for the continuous beam, there are exactly six spans of beams involved and the load analysis of the beam will involves the distribution table method in order to determine the value of moments and shears across the six spans of beams in discussion. This way, the type of reinforcement bars for both main reinforcements and shear reinforcements can be determined.
