**Project description:**

The project represents the fitting of a 3000 mc sphere on a support in
the OLTCHIM mill, for the extension of the storage space. The sphere is
supported by 11 poles placed on a circular foundation which is 4.00m by
2.50m. The poles are 1.80m by 1.80m and 6.176m high. The sphere has a
17.90m diameter. It is made from welded plates and has 11 metallic
supports, each 5.27m long, which will be fitted in the concrete poles of
the foundation.

The solution was to reposition the base of the metal poles on the
concrete foundation, but to maintain the position of the poles on the
sphere. The result was an eccentricity of the axes from the center of
gravity of the concrete poles, but after many tests, this was considered
to be the optimal solution. From the calculations, the result was that
the poles and the circular foundation could sustain the load of the
sphere, even after it has been used as storage space.
