171 Covering of cinders’ box - Ugine & ALZ Arcelor Group Project: Covering of cinders’ box - Ugine & ALZ Arcelor Group Location: Genk, Belgium Owner: Ugine & ALZ Belgium N.V. Engineering office: Ingenieursbureau Stendess N.V., Lovendegem, Belgium Contractor: Frijns Industrial Group, Netherlands Total steel weight: ± 400 tons Building period: middle 2006 Dimensions: height: ± 20 m Overall length: ± 80 m Overall width: ± 60 m Short description of the project In order to concentrate and evacuate the gasses during the dumping and storage of the cinders, a building to cover the cinder boxes had to be designed and built. The building consists of different hanging boxes, which are separated by hanging steel sheet walls. One of the critical restraints in the design was that the amount of columns had to be minimal and that existing foundations were to be used. This resulted in a building of ± 80 m by ± 60 m supported by only 7 main columns and consisting of hanging external and internal walls. Use of ESA-Prima Win Description of technical questions to be solved with ESA-Prima Win The challenge in this project was to design a low budget steel construction taking into account the existing foundations and the severe restrictions that were to be met such as a minimal number of columns (7 main columns), maximum free height inside the boxes and the maximum use of existing steel profiles. Because of the great amount of braced structures a non-linear calculation was needed. Finding the balance between a low cost structure and taking into account the severe restrictions was a high creative demand in the static layout and the dimensioning of the structure. Description of our experience with ESA-Prima Win when realizing the project. For this project ESA-Prima Win proved its power to calculate at highspeed large structures with a great number of elements and a great number of combinations. More, ESA-Prima Win proved that even for large structures the nonlinear calculations could be done in an acceptable way and time. Used modules: • Base • 3D frame • Non linear calculations • Steel code check (EC3) Covering of cinders’ box In order to concentrate and evacuate the gasses during the dumping and storage of the cinders, a building to cover the cinder boxes had to be designed and built.
