Reinforced concrete building design project & project based learning (case study) / Nurul Amyra Mohd Huzain

In designing a double storey terrace house, the Architecture drawings are obtained first from of the developer company which is TEMOKIN DEVELOPMENT SDN BHD. The structural plans are then produced by tracing the architecture drawings key plan. The size of, column pad footing and thickness of slab are determined first before all the structure elements of the building are designed in manually and in ESTEEM. Staircase is only design manually and represent as void in the ESTEEM. In this project, not all structure was designed. Only selected slab, beam, column and pad footing are designed. The first structure designed is slab. This is because we need to calculate the load that going to transfer from the selected slab to beam in order to design beam later. The load is transferred beam slab to beams by distributing the load over the beam. The slab load (permanent and variable), expressed in units of weight per area, is converted into weight per length of the. The slab should rest on the beam that carries its weight. After get the value of load transfer from slab, beam were analysed and designed to get the moments that used to design the column. The beam designed is continuous beam and the must be rest at the chosen column. The column are then analysed and designed by using the moment value from the beam. The classification of column is checked weather the column is braced/ unbraced and slender/ non-slender. The axial loads from roof floor column the stump are calculated to get the load transfer to pad footing. From load transfer by column, the pad footing then designed. The soil bearing capacity should be calculated first in project 2. This is because soil bearing is very important in order know the soil strength weather it can cater the entire load from the building or not. The size of footing is determined and the arrangement of steel bar at pad footing was identified. After designed all the structure elements in manually and ESTEEM, a comparison is done to the value of percentage error. The accepted percentage error should not exceed 30% in order to know the manual calculation is wrong or correct. However, there are some calculations that exceed 30% of error after designed the structure. The percentage error occurred because some formula or ways to determine the design value are different between two methods and it may contribute to different output of value. The ESTEEM also should check in details if any error happen. The error may occur from wrongly input the project parameters at ESTEEM. For example, the size of link used to design the beam is different in manually and ESTEEM which 8mm is in manually and 6mm in ESTEEM.
