[abstract of content] :The genetic algorithm is used to optimize the threshold and weight of neural network, and the optimal weight and threshold can be selected through fitness function. This method can explore the relationship between the content of trace elements in the rebar and the mechanical properties of break elongation, tensile strength and yield strength, and the optimum content after optimization is close to the actual production, which is helpful to the study of the optimized composition of rebar components.
