In order to solve the reliability problem of structural damage equation,a damage detection method based on ridge estimation and L-curve was presented. Firstly,a structural damage equation based on modal strain energy sensitivity was described. Then,considering measurement noise easily making the damage equation be ill,the ridge estimation was utilized to solve the damage equation and L-curve is utilized to identify optimal ridge parameters. Finally,an improved ridge estimation method was proposed to enhance the identification precision. Simulation results demonstrated that the proposed ridge estimation and L-curve methods can detect structural damage locations and level with good accuracy,their quantitative detection results are obviously better than those of the basic ridge estimation and L-curve methods and the truncated singular value decomposition method.
