Abstract

Recent large earthquakes (eg, the Mw7.2, 2011 Van, Turkey, earthquake and the Mw6.6, 2017 Muğla, Turkey, earthquake) have shown that the vulnerability of slender masonry minarets under seismic loadings . The response of minarets to seismic excitations are different from other form structures because of their complex behavior due to geometrical changes in the cross section of bodies, height and slenderness ratio. The purpose of the present study is to evaluate the effect of slenderness ratio of masonry minarets when they are subjected to ground motion and to quantify the impact of this parameter on structural demands, such as top displacement, stress and torsional moment. To this aim, six masonry minarets with different height and drum diameter were numerically created and subjected to synthetic seismic loadings created for four ground motion levels. As it is difficult to determine the slenderness ratio for varying diameters, it was investigated in two ways.
