Estimation of the Period of Vibration of Existing RC Building Types Based on Experimental Data and Numerical Results

Abstract

These relationships have been developed keeping in mind force-based design. For this reason, they provide low estimates of period such that the lateral shear force is conservatively predicted from an acceleration spectrum. On the contrary, in displacement-based assessment, the displacement demand is required, being better correlated to the expected damage. This displacement would be underestimated using the aforementioned period-height formulae (Crowley and Pinho, 2004).
