The ground motion, which is one of the environmental problems that takes place since the work area of mining sector increasingly gets included in urban areas, is becoming a popular issue, recently. Studies which are conducted for examination of potential damage risk of blasting based vibrational effect on existing surrounding buildings mostly focus on field and blasting parameters and partially on general parameters of the buildings. The aim of this study is to review the effects of vibrations due to blasting activities on structural behavior. In the scope of study; displacement parameters, which are obtained as a result of numerically testing of a large number of vibration records obtained by experimental methods and have different frequency and acceleration values on a reinforced concrete construction model that constitutes the research subject, were determined and compared to maximum displacement data targeted as the result of design loads. In the performed dynamic analyses, it was determined that the displacement values under the blasting effect of the reinforced concrete frame construction within the examination scope were quite lower than the design and displacement values obtained according to regulations and standards valid for the location of the said construction. It was identified that blasting based vibrations did not create a damage risk for the construction located at the distance of performed measurements.
