Pasargad resistance to 7 magnitude earthquake

Achaemenid engineers 2,500 years ago, to prevent the collapse of the structures of the Pasargad complex, which were built in the earthquake-prone region, used an innovative method called "two folds", which is used today in the construction of nuclear power plants and sensitive structures. It becomes.

The two-folder foundation method is a technique in structural and earthquake engineering that experts use two foundations on top of each other before constructing the structure.. The first foundation is fixed and the second foundation is built on the first foundation and has the ability to vibrate.

استفاده از این روش باعث می‌شود که مقاومت سازه‌ها تا بیش از هفت ریشتر بالا برود و در هنگام زلزله با حرکت سازه‌ها در قسمت پی، ضربه زلزله گرفته شود و سازه آسیب نبیند. This method is currently used in the construction of sensitive structures in earthquake-prone countries, including Japan..
