Abstract
The aim of this project dissertation is to design selected pre-engineered steel
structural members including rafter and column with non-typical section by using two
different design standards which are British Standard 5950 (BS 5950-1-1: 2000 “Code
of Practice for Design – Rolled and Welded sections”) and Eurocode 3 (MS EN 1993-
1-1: 2010 “General rules and rules for buildings”. The advantages and disadvantages of
design using Eurocode 3 including cost effectiveness of the design compared with BS
5950 are determined in this project dissertation. The findings show that design using
Eurocode 3 experienced lower structural performance in initial analysis but higher in
final analysis compared to design using BS 5950 for critical combination. The
structural capacities of Eurocode 3 design including shear capacity, axial capacity and
moment capacity for the section used in this analysis are higher than BS 5950 design.
Although the stable length for haunch in Eurocode 3 design is longer than BS 5950
design, the structural stability of Eurocode 3 design including the resistance of lateral
torsional buckling and resistance of buckling due to interaction of axial and bending
moment are lower compared to BS 5950 design. Lastly, Eurocode 3 design consumes
0.88% more still weight than BS 5950 design. This is because larger section sizes are
required for Eurocode 3 to fulfill all requirements. Therefore, it can be concluded that
BS 5950 design is cheaper than Eurocode 3 design.
