Ivan Guba Email: [email protected] My company IGUBA was established in 1997. I am a static engineer, 47 years old and am working alone. My annual turnover is between 20.000 and 30.000 Euros. Areas of competence: • Structural engineering • Civil engineering: all about static and construction • Design of the static of residences and commercial buildings • Diagnostics of bearing constructions • Technical consulting Projects since 1990 • Lift shaft of 120 m height for Boiler Steam Structure? 2x500 MW in Shen-Tou • Some platforms for Boiler Steam Structure? 2x360 MW Jorge Lacerda IV (Brasil) • Reconstruction of Bank “METROPOL”, Bratislava (Slovakia) • Steel Structures of many Tank- and OilStations “AVANTI” (now SHELL) in Slovak Republic, Czech Republic, Hungary, Austria, Rumania, etc. •Commercial building “Swietelsky” in Bratislava (Slovakia) •Secondary Combustion Chamber & Steam Boiler and Flue Gas Cleaning in Nyborg (Danmark) - see my project in SCIA USER CONTEST Book 2002, p. 80 Technical data of the project This project contains the static of a 750 t heavy steel structure (S235) and a 750 t heavy concrete construction (B30 and B40) for the Commercial and Business Building “ATRIUM - House of the Furniture” in Bratislava - Slovakia, where the steel structure was mounted from January to September 2003. The total length of this structure is 102,90 m, the width between 8,25 to 20,50 m, the area 1550 m² and the volume more than 40.000 m³. The building costs have been 4.000.000 Euro. Description of the Steel structure The static system is a space frame in both directions. The steel structure consists of two main dilatation structures and 13 modules (6 + 7) with a length of 7,50 m. The steel structure consists of 41 main columns, connected to one another with horizontal beams on levels of relevant floors and minimum cross bracings - due to architectural de-sign. The steel structure is designed as a self-supporting static system, which is able to transfer horizontal and vertical forces into the foundations and into the two steel-concrete boxes for both of the main dilatation structures, which create a stable unit due to its rigid walls. The access to relevant floors is enabled in these steelconcrete boxes via sideways concrete stairways and lifts. The steel structure is open at the ground floor, here garages for cars are foreseen. On the following floors the walls are clad with ALU glass- and thermo- panels. The constructional height of every floor is 4,20 m. Wall cladding is stiffened by auxiliary columns and cross- bracings between elevations +3,00 and +13,70 m. Description of the Parts of the Steel Structure The main columns are designed of broadflanged beams HE600A (0. to 3-th floor) and HE300A (4-th to 5-th floor). There are erection joints on two elevations of the structure. Transversal beams are made of open-section rolled steel beams. The connection of col-umns and beams is made by means of steel sheet flanges and bolts. The floor beams are made of open-section rolled steel beams. The various parts are connected with bolts in the erection phase. The beams are secured against yawing with profiled sheets with a thickness of 1 mm under the steel concrete floors. Why is this Project so important? The individual floors serve as exhibition and sales areas for luxurious furniture goods. The lower area is an enormous parking space for cars, by means of a lift the client has direct access to the exhibition and sales areas without having to leave the building. The main en-trance is accessible from the street through a bilateral platform, one of which serves as an entrance for the disabled. All the floors are connected, both by lifts and inclining planes, all visible from the outside through the glass façade. The highest two stories serve for the management and offices. The building is filled with highlevel furniture, a new market seg-ment in Slovakia. With its architecture, significance and supply of goods, this sales space is therefore meeting the requirements of even the most demanding clients. Why is this Project so special? Frame cross beams in the main modulus axes are positioned in transverse direction, they are so-called cellular beams of an overall height of 900 mm with circular apertures of diame-ter 600 mm. Cellular beams are manufactured with a specific technology on special produc-tion lines, on order, from IPEprofiles 500 mm. After long negotiations with the investor and the architect, the steel structure was designed from steel, fully revealing, without any hiding structures. Severe aesthetic demands were imposed with regard to connections, surface, dress114 Company Project Atrium furniture store SCIA User Contest 2005 / Commercial and industrial building 3 Categorie
