In this paper, the conditions for the existence of damage locating vectors are proved, the formulae for calculating the characterizing stresses of beams, columns and braces are derived, and the simplified calculation of modal mass-normalization constants of damaged structures is improved.

A flexibility-matrix-based damage index FDI(flexibility difference index)was developed to determine damage regions,the damage locating vectors method was utilized to locate damaged elements,and the second-order eigensensitivity analysis was employed to estimate t.

This approach is comprised of the damage locating vectors method and eigensensitivity analysis.
