Scientists have uncovered the secret of the stability of the Leaning Tower of Pisa
A group of Italian researchers revealed the long-standing secret of the stability of the Leaning Tower of Pisa, according to the website of the University of Bristol.
Despite the five-gradient slope, the 58-meter tower since 1280 experienced at least four strong earthquakes.
After studying the features of the landscape and the structure of the architectural phenomenon, scientists from the Roma University of Rome found that the stability of the tower is provided by effects associated with the dynamic interaction "construction-ground."
The considerable height and rigidity of the tower interact with the soft ground at its base, noble to which the architectural structure does not come into resonance with the earth during the tremors, the researchers say.
