Özet

Historical structures are vulnerable to effect of earthquake, wind, flood, fire, etc. Considering the active seismic resources owned Turkey, earthquakes especially important threats for historical structures. Therefore, the structural response of historical structures should be investigation under seismic effects. The most important factor in investigation of seismic response is selection of appropriate earthquake ground motion records and scaling to target design spectrum. The aim of this paper is investigation of the seismic response of historical structure based on earthquake ground motion scaling method. The historical masonry clock tower in corum, Turkey, is selected as an example. This paper presents scaling of the real earthquake ground motion records selected from the region according to the target design spectrum by applying the time and frequency domain scaling methods specified in the 2018 Turkey Building Earthquake Code. Linear time history analyses of the clock tower are performed in unidirectional (only horizontal components on the 1(st) mode direction) and bidirectional (combination of horizontal and vertical component) by using scaled ground motion records. At the end of the analyses, the effect of vertical ground motion and ground motion scaling methods on the seismic response of the masonry clock tower is evaluated. The maximum displacement, principal stress and strain values are examined comparatively according to the relevant regulations. It is observed that earthquake ground motion records are matched the target design spectrum better by using frequency domain scaling method. The results also show that maximum displacement and principal stress values obtained by scaled records according to frequency domain scaling method are higher. It is seen that the vertical ground motion records should be taken into account in the evaluation of the seismic response of the structures.
