Özet

The influence of various types of foundation soil on dynamic behaviour of reinforced-concrete 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.
