Damaged cable and concentrated load progressive identification method based on generalized displacement space coordinate monitoring

A damaged cable and concentrated load progressive identification method based on generalized displacement space coordinate monitoring includes: monitoring support generalized displacement, cable structure temperature, environmental temperature and concentrated load variation degree to determine whether a mechanical calculation reference model of a cable structure needs to be updated or not so as to obtain the mechanical calculation reference model, including the support generalized displacement, the concentrated load variation degree and the damage degree and the temperature of a damaged cable, of the cable structure. On the basis of the model and according to the approximate linear relations existing between the current value vectors of to-be-monitored parameters and current initial value vectors of the to-be-monitored parameters and between a unit damage to-be-monitored parameter value variation matrix and a to-be-determined current nominal damage vector, the influence of interference factors can be removed
