Our paper deals with structural optimizing by new discrete searching technique. The goal is to find the best discrete optimizing parameters subjected to mass minimizing and multiaxial fatigue damage. Equivalent stress for using biaxial problem and rainflow decomposition is calculated by so called integral approach. The necessary coefficients in this process are found by using special optimization way.
