Optimum Design of Prestressed Concrete Beams

Optimum Design of Prestressed Concrete Beams P. B. R. Dissanayake and S. Jothy Karma Abstract: One of the motivations in optimizing structures is to reduce the overall weight, which often results in reduced material cost. Efficiency implies minimum cost or minimum weight while satisfying a variety of strength and stiffness requirements. In all engineering problems, designers try to find ...

Genetic Algorithms, a relatively new technique of optimization, is used for the optimum design of prestressed con¬crete beam. Prismatic unsymmetrical I-section girders, simply supported at the ends and subjected to a uniformly distributed load are considered for the optimum design. The total cost to be minimized includes the cost of high strength concrete, high tensile steel and a cost to ...
