Abstract
In this study, the effects of vertical ground motion on the seismic responses of historical masonry structures are numerically investigated. To this aim, a historical mosque subjected to the 2011 Van Earthquakes and their aftershocks is considered. These seismic actions caused devastating damages to the minaret, the main dome covering the prayer place, and the porch sections of this mosque. The seismic behavior and structural responses of the mosque are evaluated by using linear time-history analyses. The ground motions recorded Van Earthquakes (23 October 2011 (MW=7.1) and 09 November 2011 (MW=5.7)) are used. Analyses of the mosque are conducted considering both only horizontal components and all components of the earthquakes. The displacements, absolute accelerations, and tensile stresses are handled as comparison parameters. As a result, it can be clearly seen that the vertical components of 2011 Van Earthquakes significantly modify the seismic behavior and structural responses of the inspected structure.
