【Abstract】 In this paper, an efficient method for bridge damage detection is developed based on experiment modal analysis. The paper reviews the basic theory and development tendency, compares the sensitivity of modal parameters and stress-strain parameters, and points out stress-strain parameters have superiority on bridge damage detection in practise.更多还原
