Study on the non-destructive detection techniques and damage identification method is of great importance
in protecting and rehabilitating the ancient architectural structure. In order to identify the location and the
grade of structural damages, a multi-point microtremor measurement is performed on carved brick screen walls at
Songjiang area in Shanghai, and the observed dynamic parameters (natural frequencies and natural modal) are
obtained. On the other hand, the dynamic parameters of the original structure are calculated by finite-elementmethod
(FEM). Normalizing the observed and calculated parameters on unified physical quantity, the damages
are located by the variation on vibration modal, and the grade of structural damages is quantitatively evaluated
by stiffness losses based on the variation on vibration modal.
