Abstract

This paper presents the comparison of the American Concrete Institute (ACI), British Standard (BS) and Eurocode (EC) in the optimal design of a simply supported prestressed concrete beam. The technique utilised in this research is the piecewise linearisation method in which the non-linear equations are being simplified to linear ones and they are eventually solved using the simplex method. The objective of the optimisation is to minimise the weight of the beam which at the same time will optimise the amount of materials used and therefore will produce the most cost-saving beam. The constraints are developed from the design requirements, restrictions and limits as stipulated in the relevant code of practices. From the results obtained in this study, it has been found that the prestressed concrete design based upon the ACI requirements is more economical than that of EC, with BS being the least economical design.
