Özet: The purpose of the Evolutionary Structure Optimization (ESO) method is to achieve the optimum structure in terms of weight and stiffness with uniform distribution of stresses in the structure. ESO methods for building design, the elements in the initial design field are generated by subtraction within certain criteria in a loop. This loop is repeated until the ideal design is obtained. The obtained ideal model can be acceptedas the optimum model for the Strut-and-Tie Method (STM). STM is a method that turns the beams into a rod system and assumes that the elements behave like a parallel-horizontal rod. In this study, optimum design samples with obtained by Evolutionary Structure Optimization method was investigated for suitability of Strut-and-Tie Method on bridge beam subjected to different loads. In addition, optimum design samples are presented for different loads. In the ESO method, the element removal loop is carried out by using ANSYS finite element software.
