AbstractThe first four lateral modes and frequencies of vibration of a 15-storey reinforced concrete building were obtained from an analysis of wind-induced vibration measurements. The building consists of flat slabs supported on columns and shear walls. Theoretical values of the vibrational modes are calculated using different structural models and considering upper and lower bounds of floor weights and material properties. For some select models, the influence of foundation compliance in the rocking and sliding mode is also investigated theoretically. Results indicate that changes in modal frequencies may be substantial for practically realizable variations in material properties. Measured frequencies of the building fall within the calculated frequency bounds for one particular mathematical model. It is also demonstrated that the frequencies of the lower modes of vibration may be decreased significantly by foundation rocking.
