There are several published analytical and empirical formulas for the vibration period of buildings. These formulas primarily depend on the building material, building type and overall dimensions. Although these formulas are proposed for use in design process, correlation of estimated periods with the ones obtained from detailed finite element modeling of the structural system appear to be too weak. It is believed that the poor performance is primarily due to inappropriate use of these formulas and inadequacy of the parameters used in these formulas. In this study, the period formulas given in the codes and the literature are evaluated using the developed shear wall building models and the databases employed by other researchers. The adequacy of the available formulas was evaluated through comparisons with the periods measured and analytically calculated for the databases of the building models employed. The parameters used in existing formulations were found to be inadequate for buildings having frame-wall interaction. In buildings where frames contribute to the lateral stiffness a term that incorporates the effect of dominant deflection mode of the structure as a result of frame-wall interaction needs to be incorporated in the formulations.
