Abstract

Because of the many advantages, using of self competing concrete (SCC) in structures is increasing. Construction of precast-prefabricated components, with the use of concrete has also recently been considered. Concrete properties have significant role in precast-prefabricated girders behavior. Exact prediction of these properties is the base of members analysis and design. Determine the optimum composition is the mean to obtain the best set of useful concrete properties. In this paper, SCC mix design optimization method is presented based on multi-criteria optimization using particle swarm algorithm (PSO). The results show the Successful application of Pareto optimization method in the optimization of scc mix design used in bridge girders
