In this paper, the experimental investigation of the behaviour of Vilnius Arch-Cathedral Belfry affected by the dynamic loading induced by the operation of a modern bell system is considered. During the preliminary investigation the significant damage and multicracking in the main masonry walls of the Belfry were observed. They were caused by long–term use of this historical building. In 2002, 6 new bells were installed according to a modern location scheme. It is evident that the bells produce different dynamic effect on this historical building, which has not been investigated yet. The dynamic investigation was conducted to predict the behaviour of the structure considered. Mass accelerations of Belfry structures were measured during the dynamic investigation. A contribution of dynamic effects was evaluated in terms of response spectra. The results obtained were thoroughly analysed and the appropriate remarks and conclusions were provided. |
