A method that estimates stiffness matrix, mass matrix and structural mode of building from modal test data is presented, also the calculation of damage location and quantity from modal test data in damaged building is proposed in this paper. The method to estimate stiffness matrix and mass matrix depends on measurable points that are less in number than the total structural degrees of freedom. Based on this method modal data of unmeasurable points are estimated, then global stiffness and mass matrices of structure are obtained by using the frist two orders of modal data. Damage location index is calculated by mode-stiffness of the measured modal data in damaged building and estimated modal data using this method. Damaged stiffness quantity is calculated by modified stiffness in damage location index. Finally, examples is studied in this paper. Its result shows that a method of calculation damage location and quantity using modal data measured in damaged building is reliable.
