Project Description and Construction
The dimensions of the plant in the ground plan are about 33 m x 35 m (108 ft x 115 ft) with a height of 15 m (49.2 ft). The top level of the continuous casting plant to be newly constructed is called the casting platform and is designed for a load of 3 t/m² (3.3 t/10.76 ft²).
There are control rooms on the casting platform and emergency buckets (which collect the molten steel in case of failure), as well as crane runways and other transportation equipment.
The supporting structure consists of steel girders with a span of up to 14 m (50 ft). The biggest main beams have dimensions of h x w = 1200 x 600 mm (47.2 in x 23.6 in) with plate thicknesses of up to 60 mm (2.4 in). The structure is reinforced against seismic loads by diagonals.
Structural Analysis and Design
In order to implement the planning of the extension quickly and effectively, the possibilities of digitization and data exchange between the various 3D planning and calculation programs were used right from the start.
The existing construction was first captured with a 3D laser scanner and was displayed as 3D point cloud. It was transferred to an RFEM file using a construction program with the import/export function as an intermediate step. The model was thus available as a basis for further analyses.
The structural analysis was performed according to Eurocode 3 in the RF‑STEEL EC3 add‑on module.
For a detailed display of the results, the graphical tools of RFEM were used; for example, to classify different categories of reinforcements and to display them in color in 3D graphics.
