“…The reason is that, in addition to the intrinsic properties of the column, the frequency content, duration and amplitude of the earthquake excitation may also greatly influence its structural response. As in the case of conventional modern structures therefore, much research has been devoted to the proper selection of earthquake records (Katsanos et al 2010;Sextos et al 2011) and the efficiency of different Intensity Measures (IM) that are commonly used in the framework of seismic vulnerability assessment (Shome and Cornell 1999).…”

This paper deals with the dynamic response of a free-standing ancient column in the Roman Agora of Thessaloniki, Greece as a means to shed more light on the complex behaviour of rocking bodies under seismic excitation. Numerical analyses utilizing discrete element method were carried out with the use of multiple seismic records selected based on the disaggregation of the seismic hazard for the region of interest. To identify their impact on structural performance, earthquake Intensity Measures, such as Peak Ground Acceleration and Peak Ground Velocity are examined for the case of a column that sustained no visible permanent deformations during the Ms = 6.5 Thessaloniki earthquake of 1978. The analysis revealed a weak correlation of PGA and PGV with the response results and a significant influence of the mean frequency (f m ) of the seismic motion. No coupling was found between the maximum displacement of the top during the oscillation and the permanent post-seismic deformations. The complementarity of both earthquake Intensity Measures in the structural vulnerability assessment is also depicted.

Abstract. This paper investigates the variability of the seismic response of structures subjected to various ensembles of ground motions in the framework of nonlinear dynamic analysis. In this kind of analysis, seismic loading, introduced in the form of excitation accelerograms, constitutes the most important source of uncertainty, as it depends on a number of random factors (e.g. distance from the fault source, magnitude, local soil conditions). In order to quantify the effect of seismic loading simulation on the response variability of structures, nonlinear dynamic analysis is carried out on a steel frame, subjected successively to three ground motion ensembles. The ensembles comprise, respectively, real ground motions and artificial accelerograms generated by two different algorithms, one in accordance with the Code provisions and one targeted to a more realistic simulation of the seismic event. Comparison of the three approaches is made by monitoring the statistical properties of the maximum displacement and interstorey drift induced by the assumed ensembles.

“…The purpose is to compare the structural response with and without a theoretical implementation of the TMD. For that linear elastic dynamic time history analysis will be conducted, which is also very useful when dominant modes are closely spaced or for multiply supported structures (bridges) where higher modes are expected to be excited, due to the asynchronous nature of incoming seismic waves [1]. Time-domain is prescribed in the majority of seismic codes around the world, as so in the Eurocode 8-1 (EC8-1) [2].…”
