A steel building at the cement plant of AGET Hercules in Chalkida, belonging to the Lafarge Group of companies.

The building houses the raw materials of additives used in cement production.

It is an essential building for the storage of about 60,000 tons of additives, but also for the protection of the environment from dust.

The span of the “four-stringed” truss frame structure is 54 meters and the height of the frame reaches 27 meters.

It consists of square hollow sections (SHS) from 60 to 180 mm. It was transferred to the construction site in individual blocks which were pre-fabricated in the factory.

The frame is distinguished by its minimal weight and slenderness.

The building comprises a total of 13 such frames, 11.65 meters apart, as the total length of the building is 139.8 meters.

The frames are based on reinforced concrete columns, which are connected to each other with a reinforced concrete peripheral wall 3,0 to 5,0 meters high.

The foundation consists of individual flat pad footings, connected to each other by longitudinal reinforced concrete elements.

The necessary increase in the stiffness of the steel roof between the frames was achieved by the application of “three-stringed” truss “beams”.

The erection of the building was relatively easy, due to the low weight of its components, the simple layout of the building and the absence of in-situ welding.

During the construction of the individual parts of the building at the factory, detailed checks on the quality of the welds were carried out.

Erection was done with absolute safety, in a short time and the result meets the highest quality standards.
