The objective of many of damage detection methods is to detect the damage occurring on the structure.for example, stiffness reductions in the damage location of the structure.However.the integrity and safety, of some particular structure, for example, cantilever beam-like structures, can be seriously affected by damage affecting their boundary conditions.In the field of boundary condition parameter identification, two model updating methods, i.e.method based on the characteristic equation and method based on sensitivity analysis of natural frequency and mode shape.
