A group of engineering scientists from Britain and Italy announced that it found the answer to the question because it does not drop the 58-meter-long tower of Pisa dating back to 1280 as it shows a 3-4 degree slope and still stands up despite the four strong earthquakes that have occurred in the area in its 500 years of existence.
Researchers attribute the stability of the Pisa tower to the soft ground on which it is built. “The irony lies in the fact that this soft soil that caused the gradient and brought the Tower to the brink of collapse was what contributed to it to withstand seismic influences,” says one of Bristol University researchers, Professor George Mylonakis.
According to engineers, the combination of the rugged construction of the Tower and the soft ground during the earthquake does not create oscillations. As a result, this construction has almost the best indicator of so-called dynamic building and soil interaction, with which engineers assess the stability of a building during an earthquake.
Professor George Mylonakis from the Civil Engineering Department of Bristol University was invited to participate in a group of 16 researchers under the supervision of Professor Camillo Nuti of Rome Tre University to study the mystery of the Pisa Tower , which has troubled engineers for years.
The results of the study of 16 British and Italian engineers have already been presented to an international working group and will be formally announced at the 16th European Conference in Earthquake Engineering
