The earthquake ground acceleration and the acceleration response histories of various floors of buildings are required as input. The method evaluates the modal parameters like the eigen frequencies and mode shapes using a sub-space iteration technique (N4SID) after appropriate re-sampling and filtering of the recorded response. Using the Least Square Technique, the stiffness of the structure is evaluated and localized damage can be identified, if present. The method of system identification proposed in this study is capable of identification of system parameters of buildings with non-uniform mass and stiffness distribution. The method is applied for identification of a nine storeyed reinforced concrete building of BSNL Guwahati instrumented with limited numbers of sensors. Structural response data recorded during earthquakes on 11th February and 12th August, 2008 have been used for identification of system parameters of the building.
