The primary and main objective of the structural designing is to achieve safety and economy, the conventional design methods achieve the safety factor but it is not that much easy to achieve both the objective at the same time so the optimizations techniques are developed by researchers to achieve the safety and economy. In most of the studies the optimization techniques are used to minimize the cost. In this paper the optimization technique is used to obtain the optimum weight of the prestressed concrete beam by using genetic algorithm. I-section beam is used in this paper and design for optimum weight. Generally the idealized I-section used in previous studies due to simplicity of section in this study the general I-section beam is used with 8 design variables and 13 constraints. The computer program for genetic algorithm optimization method can assist the designer to achieve optimum values of design variables rapidly and easily.

Key words: prestressed concrete beam, idealized I-section beam, generalized I-section beam, optimization, genetic algorithm, weight optimization and cost optimization
