In this study, modal parameter identification under multi-operational grades was proposed to simultaneously eliminate the effect of environmental factors (traffic load, environmental temperature, environmental humidity and wind load etc,) on the modal parameters of bridges. A cluster method was applied to classify the monitoring modal parameters, obtained by using the long-term monitoring data of bridges, into different grades. In each grade, the relationship between modal parameters and environmental factors could be deemed as a simple linear relationship, and then the classified modal parameters could be applied to detect the damage of bridges under the effect of environmental factors. Finally, the long-term monitoring modal parameters of a practical bridge were applied to demonstrate the effectiveness of proposed method.
