This system is very attractive for the medium to high-rise buildings with repetitive plans due to satisfactory performance during past earthquake, industrialized modular construction technique, low cast and also saving in construction time. Recent studies show that the current seismic codes and guidelines do not provide sufficient requirements for seismic design of these structures. The designers ought to adopt the traditional force based design methodology of framed structures for tunnel form. In this methodology, the fundamental period and the proposed behaviour factor (R factor) are used to compute the design base shear of a structure. Most seismic codes specify empirical formula to estimate the fundamental vibration period of building. Prior studies have shown that the empirical equations for predication of fundamental periods of this specified type of structures, may yield to inaccurate results. Some of new equations were suggested and a varied rang of parameters were considered to achieve a certain formulas. In this study, the fundamental period and mode shapes of tunnel form buildings, one of the basic parameters of seismic behaviour in linear response was investigated. Previous suggested formulas were studied and compared with each other. Some finite elements analysis carried out to show the influence of each parameter on the fundamental period. The results showed that the IBC 2006 formula for estimating the period of this type of structures, is still more reliable than other formulas which derived by different authors in recent studies.
