This paper proposes a model-based state observer to perform high-definition response estimation in partially instrumented building structures. The proposed estimator is verified in a simulated five-story shear-building structure and validated using measurements from a seven-story reinforced concrete building slice tested at the NEES-University of California at San Diego shake table. In both cases the proposed estimator yielded satisfactory results by estimating the time history of shear forces, bending moments, displacements, and strains at various points/sections of interest. The proposed algorithm can be used in instrumented buildings for various practical applications such as post-earthquake damage assessment, structural control, and building code calibration.
