Abstract
Finite element model of Harbin Sifangtai Bridge was established, eight accelerometers with force feedback were applied to measure acceleration of bridge deck by the way of group test; piezoelectric accelerometer was applied to measure acceleration of cable; and the combined method of NExT and ERA was applied to identify the cable-stayed bridge modal parameters. The identification result was compared with the calculated result by FEM. Frequency difference fitting method was introduced to identify frequency and tension of cable and the result was compared with the designed cable tension of real bridge.
