A multistorey high-rise building has been monitored using microradian precision inclination sensors and the structural movements have been analyzed as consequence of 40 days observation period. In the first step, the time series obtained from inclination sensors' data were processed with Least Squares Spectral Analysis technique. In documenting the periodicity of the data, the correlation functions were also used as a straightforward way of evaluating the time series. Afterwards the results from the analysis were interpreted and linked to the other observed data such as temperature changes, wind load effects, population in the building and instant earthquake information in the observation period. Further on the results were compared with processed data from consecutive GPS campaigns processes. The study has shown that precise inclination sensors are efficient tools for continuously monitoring and investigating structural movements of large engineering structures.
