“…Recently, a study was conducted by the authors to investigate the seismic response of reinforced concrete (RC) minarets (Sezen et al 2008). Linear elastic dynamic time history analyses were conducted using a RC model similar to the first model used in this paper.…”

“…For example, the flexural strength of an unreinforced masonry model is significantly lower as the reinforcing steel in a similar RC model provides tensile resistance. While Sezen et al 2008 investigates distinct parameters affecting the behavior of RC minarets using a single model, this study examines the effect of masonry material properties and minaret height on the minaret response using three different models. …”

Almost all historical minarets in Turkey were constructed using cut stone, masonry blocks or combination of these two materials. The structural and geometrical properties of each masonry minaret, or slender tower structure, depend on many factors including the structural knowledge and applications at the time of construction, experience of the architect or engineer, seismicity of the region, and availability of construction materials in that area. Recent earthquakes in Turkey have shown that most masonry minarets in high seismic regions are vulnerable to structural damage and collapse. In this study, in order to investigate the dynamic behavior of historical unreinforced masonry minarets, three representative minarets with 20, 25, and 30 m height were modeled and analyzed using two ground motions recorded during the 1999 Kocaeli and Duzce, Turkey earthquakes. The modal analyses of the models have shown that the structural periods and the overall structural response are influenced by the minaret height and spectral characteristics of the input motion. The dynamic displacement and axial stress time histories are computed at the critical points on the minarets. During recent earthquakes, most minaret failures occurred above the base of the structure. Consistent with the observed response, the largest stresses were calculated at the same location.

“…The dynamic analysis and seismic performance of reinforced concrete minarets were also the subject of various studies presented in the literature. Probable cause of extensive damage to a reinforced concrete minaret was examined by gaining proper understanding about the observed failure modes and their seismic performance, and through dynamic analysis of the minaret [27]. Another damage assessment study was performed by using the wavelet packet transform (WPT) and the artificial neural network (ANN).…”

Experimental modal investigation of scaled minaret embedded in different soil typesThe influence of various types of foundation soil on dynamic behaviour of reinforcedconcrete minarets is analysed in the paper. A 1:20 RC scale model was constructed in laboratory for the testing. The gravel, sand, and clay-gravel mixture, were used as foundation soil types to determine differences in dynamic behaviour as related to the type of foundation soil. Experimental measurements were conducted using the Operational Modal Analysis (OMA), taking into account ambient vibrations due to wind action and traffic. Test results show that the dynamic behaviour of RC minaret is strongly influenced by the type of foundation soil. Eksperimentalno modalno istraživanje modela minareta u raznim vrstama temeljnog tla U radu se prikazuje analiza utjecaja raznih vrsta temeljnog tla na dinamično ponašanje armiranobetonskih minareta. Za potrebe istraživanja u laboratoriju je izrađen ab model u mjerilu 1:20. Kako bi se ustanovile razlike u dinamičkom ponašanju modela minareta ovisno o vrsti temeljnog tla, kao temeljno tlo korišten je šljunak, pijesak i mješavina gline i šljunka. Eksperimentalna mjerenja su provedena pomoću operacionalne modalne analize (OMA), pri čemu su u obzir uzete okolne vibracije uslijed djelovanja vjetra i prometa. Rezultati ispitivanja pokazuju da vrsta temeljnog tla bitno utječe na dinamičko ponašanje ab minareta.Ključne riječi: operacionalna modalna analiza, ab minaret, poboljšana dekompozicija frekventnog područja, ambijentalne vibracije Vorherige Mitteilung
