  • In view of the defects of single-location damage identifying method, the multi-location damage identifying index of cable-stayed bridge in combination with wavelet packet energy spectrum and frequency response function (FRF) was proposed. The random-fuzzy mean was processed with the FRFs of undamaged and damaged structures. Wavelet packet energy spectrum was analyzed with the processed FRFs as wavelet base functions, and the value of accumulated energy variation was extracted to recognize damages. The experiment of a single tower cable-stayed bridge model and the numerical simulations of continuous and simple-supported beams were carried out. Analysis result shows that 1 or 2-loacation damage of bridge model can be identified and located. With the increasing of damage severity, the initial damage index increases linearly, and it will change gently or dramatically when the damage severity approaches 40%-50% or exceeds 50% respectively. The damage identifying result of hammering excitation is better than that of environmental excitation, and the value of hammering exciting load has no effect on identifying precision.
