This final year project report covers the analysis of design method used in British Standards and Eurocode for the design of composite columns and simply supported beams. Starting from this year, 2010, Singapore will be using Eurocode in design of structural members. Composite members are used in high-rise commercial buildings due to its high load capacity. For a given required structural capacity, composite members are able to attain such capacity using a smaller section than that of reinforced concrete, thus, aid to save space. In design of composite members, the key point is to ensure that the bonding between the steel and concrete are able to work as a single member instead of two to prevent slippage, else, defeating its purpose. Comparing the results computed from both codes and to that of the concrete filled steel tube columns experimental data, Eurocode shows a more accurate result as British Standard tends to be more conservative in design. British Standard calculates the column failure load as a function of its squash load and buckling coefficient that is determined by the slenderness ratio of the column. In comparing the results, templates are created in Excel spreadsheet in order to speed up the computation using both codes. A disc will be attached with this report, which comprises the design of composite column; composite concrete filled steel tube columns, simply supported primary and secondary beams for both codes. With the aid of advance technology, design can be made easier and faster as compared to manual design. A more precise comparison of the technical terms with regards to the design of composite members in British Standards and Eurocode is discussed in the conclusion of this report.
