Preheater Tower and Cement Mill, AGET Heracles Volos Plant

Preheater Tower and Cement Mill, AGET Heracles Volos Plant

The Project

Two buildings, the cement mill and the pre-homogenisation tower in AGET Herakles, Lafarge plant in Volos, had to be upgraded to earthquakes. The mill building has a height of about 50 meters and its neighboring building, the pre-homogenisation about 66 meters, were made of reinforced concrete in the 70s and are separated by a joint. The aim is to limit deformation and thus damage in a subsequent earthquake.

 

This requires an increase in stiffness and at the same time an increase in the damping of the vibration energy. The proposed method provides for the incorporation of V-shaped stiffeners at all levels. At the top of the V is a metallic frame, that can be plastically deformed during the earthquake, without failing. Thus, energy is absorbed and the relative movements are reduced.

 

The process is simple, can be implemented without interrupting the plant and is particularly economical. The only problem is the presence of obstacles due to the passage of many mechanical elements in the openings of the frames. For this purpose, some changes had to be made to the geometry of the stiffeners.
