DYNAMIC ANALYSIS OF BELL TOWER WITH BELL FORCES

Dynamic Bell towers are structures dating a few thousand years ago while their structural behavior is discovered in detail only now in the last few decades. They are monuments of culture and civilization, witnessing the time when they were built but also witnessing the history of the region around them. Old bell towers are built as a masonry structures and as that stand the test of time to this day. The new ones are made of reinforced concrete, steel or combination of both materials. This research paper presents rational procedure for determination of dynamic characteristics of bell tower in order to have an insight into its true structural behavior and to check occurring of resonance during the ringing of the bells. This methodology was conducted on the bell tower of Cathedral Church „St. Clement of Ohrid” in Skopje.
