Abstract

The European Standards and British Standards are the standards used in design of structural steel. This project is about the comparisons between the two standards with respect to a flexural member design. The European Standards used for this project is the Eurocode 3: Part 1.1 (1992) or simply written as EC 3: Part 1.1 (1992). While, the British Standards used in this project is the BS 5950: Part 1 (2000). There are few methods of comparison used in this project. These methods include the notation, load factors, load combinations and design considerations, an example of flexural member design, the safety factors, economical factors, advantages and disadvantages of the two standards. Throughout the project, it is found that the notations used are slightly different from each standard. The limit states design is the design basis for both standards. The factors considered in flexural member design include shear capacity, bending moment capacity, web buckling capacity, web bearing capacity or web crushing capacity and deflection. For the EC 3: Part 1.1 (1992), an extra check on web crippling and maximum deflection, 8max which is not required in the BS 5950: Part 1 (2000). From the results, it can be concluded that the EC 3: Part 1.1 (1992) is more conservative while the BS 5950: Part 1 (2000) is more economical. However, in the real practice, both of the standards offer almost the same results in term of conservativeness and economical factor.
