The paper is concerned with the prediction of fundamental vibration periods of multistorey shear wall buildings. The determination of natural frequencies is the key issue in designing of tall buildings. The calculation of natural frequencies and mode shapes is the first step in evaluation of the dynamic response of the structure by the modal superposition technique. The values of natural frequencies are also required in the determination of equivalent static loadings due to wind actions. The comparison of estimation of fundamental vibration period from the proposed in the literature formulae has been the main aim of the present paper. The empirical equations presented in the papers [1-4] have been considered. Computations have been carried out by using the following specialised computer programs for shear wall structures: BW for Windows [5, 6] and ETABS [7]. The paper has provided the comparison of fundamental periods of shear wall dominant buildings constructed by using tunnel form techniques, the models of which were discussed in the papers [1, 2, 8]. For more than 15-storey high buildings the results of computations using the continuous model of shear wall structure agree well with finite element analysis results.
