Summary:**The invention relates to the technical field of bridge structure health monitoring and safety maintenance, and discloses a stay cable force calculation method simultaneously considering sag, dip angle and flexural rigidity, which comprises the following steps of: looking up basic parameters of a stay cable according to design data or construction data; calculating dimensionless parameters gamma, epsilon and lambda2 of the stay cable by considering the influence of the sag, the inclination angle theta and the flexural rigidity EI of the stay cable; the acceleration response of the stay cable is tested through an acceleration sensor, the frequency omega of the acceleration response of the stay cable is recognized, then the dimensionless frequency of the stay cable and dimensionless parameters gamma, epsilon and lambda2 are calculated, then the dimensionless frequency of the stay cable is substituted into a vibration characteristic equation of the stay cable, and a function relation between the dimensionless f
