The empirical formula for calculating the natural period of a structure is generally obtained by means of statistical regression after the natural period of a structure of the same type has been measured. However, the conventional methods are generally complicated. Based on the cumulative method, a new method to determine the empirical formula for calculating the natural period of the structure is proposed. The method can fully reflect the actual condition of the free vibration of the structure and obtain a more accurate prediction value of the natural period of the structure. The method is simple, practical and has broad application prospects.
