One of the projects in our country where seismic and wind protection systems have been applied is the new Flagpole at the National Flag Square.

This project is not only one of the most unique projects in Azerbaijan, but also in the world. The new flagpole, which has already entered the Guinness Book of Records due to the size of the flag and was recently inaugurated by the President, is among the tallest in the world, with a height of 195 meters.

For such a tall structure, a protection system against seismic and especially wind loads is one of the most critical components.

As ESDESCON LLC, we supplied a 3-unit, 14-ton TMD (Tuned Mass Damper) system produced by MAURER, a 148-year-old German company we represent in Azerbaijan.

This 3-stage TMD system operates depending on the intensity of the wind and seismic forces: the first stage activates under mild conditions, and stages 2 and 3 are engaged progressively as the intensity increases — thus fully ensuring the structural safety and damping vibrations of the flagpole.

According to structural calculations, the theoretical sway of the top of the pole without a TMD would be ±3 meters. With the application of the TMD, this sway was practically and theoretically reduced to ±15 cm (a 20-fold reduction).

One of the biggest challenges faced by MAURER in this project was the necessity to significantly modify the TMD structure due to the internal design of the flagpole, which includes an elevator and stairs at certain heights.

MAURER specially designed and manufactured a ring-shaped TMD system with a hollow center for this project. The loads are distributed along the inner wall of the pole and move accordingly to ensure stability.

Additionally, ESDESCON LLC supplied temporary dampers used during construction. Detailed information about these systems is available on our website.
