Abstract
Indian seismic code provides expressions to evaluate the fundamental natural period for the seismic analysis of the structures primarily as a function of the height of the building and the length of the structure along the direction of earthquake considered. Building period predicted by these expressions is very useful in practice. Many researchers have performed the studies to evaluate the fundamental natural period of the buildings and found that the different other parameters such as stiffness of the structure, base dimensions, and the number of bays also affect the value of the fundamental time period of vibration of the building. Researchers also found that there is a scope for further improvement in the presently available expressions of time period given in design codes. In this study, effects of the various parameters have been studied and derived an expression to evaluate the time period of vibration.
