A critical study on empirical period - height relationship for reinforced concrete moment resisting frame buildings

摘要

Most of the building codes provide the empirical equations to estimate period of vibration of the building. It is shown that, even though the code formulas provide periods that are generally shorter than measured periods, these formulas can be improved to provide better correlation with the measured data. The present study makes an attempt to gather the possible empirical period - height relationships for RC buildings. It points out the new trends that have become apparent, reflects on the gaps that have been missing in our knowledge and speculates on probable future studies that will allow to enlarge knowledge of this relationship.
