Seismic Response Parametric Study of Ancient Rocking Columns

Rocking Spectrum Intensity Measure for Seismic Assessment of Rocking Blocks

“…The strong dependence of the velocity characteristics of the ground motion with rocking response is verified in recent studies [12]. Also, Intensity Measures such as Housner's Spectral Intensity (SIH), containing information of the elastic response of SDOF, affects significantly the response of free standing rigid blocks [13].…”

“…Moreover, velocity based and frequency content IMs are also examined. These IMs are known that have strong correlation with the rocking response [12,13], thus the comparison of those performance with the performance of the proposed IM could assure their suitability for usage to vulnerability analysis of rocking structures.…”

“…Psycharis et al [11] have been assessed the seismic reliability of ancient multidrum columns, while Dimitrakopoulos and Paraskeva [12] have been evaluated the efficiency of dimensionless IMs in predicting rocking response. Kavvadias et al [13] have been examined several IMs in order to conclude to these that describe with better accuracy the rocking response of rigid blocks.…”

Numerical Study on the Dynamic Response of Classical Column Standing Free on an Isolated Base

“…However, due to the fact that it elongates the period of the excitation wave it could be harmful for implementation to rocking structures [19]. Moreover, it is known that the rocking response of slender blocks is affected mainly by the velocity characteristics of the excitation [11,12].…”

“…Moreover, the influence of the epistyle mass on the rocking response of the colonnade has been examined by Makris and Vasiliou [10]. The influence of the IMs in the rocking response has been also examined [11,12] The seismic risk mitigation of museum artifact and ancient structural systems form a challenging task to researchers. The intervention method has to be not-intrusive to the form of the monument.…”
