Abstract
This paper presents system identification, finite element model (FEM) development and model updating based on recorded seismic responses for a reinforced concrete building. The modal dynamic properties of the building were identified using state-of-the-Art N4SID system identification technique. To ascertain the effect and contribution of structural and non-structural components (NSCs) and soil-structure-interaction, a three dimensional FEM of the building was developed in stages. To further improve the correlation of the developed FEM and the measured responses, a sensitivity-based model updating technique was employed taking into account concrete stiffness, soil flexibility and cladding as updating parameters. It was concluded from the investigation that the participation of soil and NSCs is significant towards the seismic response of the building and these should be considered in models to simulate the real behavior.
