Vörösmarty Tér 1, Budapest, by CSM

CSM nv is an engineering, fabricating, industrial painting and erecting company that provides a complete range of structural steelwork within Europe and in various parts of the world.

ING Real Estate has developed a multifunctional block of buildings in the old centre of Budapest. Vörösmarty No. 1 is situated in the heart of Budapest, on the city’s most famous square, Váci utca.

The geometrical system composed of triangular elements makes the outlook of the building’s façade unique, modern and fresh. This structure is constructed from steel pipes of varying cross-sections climbing around the building in a triangular shape covered with clear glass.

The internal forces and reactions obtained from Scia Engineer were used to calculate the connections (steel-steel and steel-concrete).

Winter Garden of Royal Greenhouses, Brussels, Belgium, by VUB

The project concerns a structural restoration study of the Winter Garden of the Royal Greenhouses of Laeken, Belgium. The Winter Garden was built between 1874 and 1876 under the authority of the Belgian King Leopold II. These greenhouses have a high cultural and historical value due to their importance in the development of structural steelwork in Belgium and Europe. In this student thesis a 3-dimensional computational structural analysis is carried out which allows for verification of the current structural state. The study includes identification of the geometrical and material parameters of the structure, determination of the symmetrical and asymmetrical load cases and evaluation of efficiency under all load combinations. The complete analysis is carried out according to the current European standards: Eurocodes EN1990, EN1991 and EN1993. Based upon the results of the structural analysis, different possibilities for the restoration of the construction of the Winter Garden are presented.

La salle des machines de l’EPR, France, by Baudin Chateauneuf

The project relates to the implementation of an engine room for a new-generation nuclear reactor, the EPR (European Pressurised Water Reactor). It is 120m long, 60m wide and high and includes over 7,000 tonnes of steel. The lower part of the engine room includes many technical floors, whereas the upper part, with the top of the turbine generator set, forms an immense nave with an overhead travelling crane of 51 metres range and 300 tonnes lifting capacity.

This project represents a double challenge, both in its technically exceptional dimensions and the fact that it is the first project the company has calculated in Eurocodes.

The principle of overall stabilisation of the structure by the floors required the use of a full 3D model of the structure. The analysis of the results of the linear and seismic analyses mobilised all the energy of the Steel Frames Department in order to allow for the beginning of the assembly of the framework in June 2008.

North Freight Area - Liège Airport, Belgium, by Lemaire

In order to expand its activities, Liège Airport has decided to develop its ‘North Freight Area’ by building a new hall. The building has a total space of 12,500 m2 and also includes offices. The area is divided into two parts that are completely similar, in this way two different companies can work independently of each other.

The steel structure contains beams with the length of 25 and 28 metres. There are only four columns inside both areas. This makes the operational work of handling goods very easy.

The structure has been optimised using Scia Engineer software, with the more specific calculations based on EC3.

Cable bridge Dilsen-Stokkem, Belgium, by Stendess

The bridge is built to cross the Zuid-Willemsvaart between Dilsen and the new industrial zone of Lanklaar, the IQ-park. It can also be considered the “missing link” in the renowned and busy bicycle route network of Limburg.

The 88-metre-long bridge deck is supported by 2 x 8 cables connected to the top of an A-framed curved pylon. The curved pylon is 43m high and has the width of 11.50m at the base.

The stability of the pylon is guaranteed by 2 x 3 cables which go backwards to a big concrete foundation.

The pylon and bridge were completely assembled in the workshop. Two pontoons transported the two pieces to the site and were used for the erection. Following the assembly of the pylon, bridge deck and cables, the concrete slab on the deck was completed.

A steel code and stability check according to EC3 has been carried out for this project.

Bow-string bridge of Beek te Bree, Belgium, by SBE

The project relates to a bow-string bridge in Beek, near Bree (Belgium). The overall length of the structure is 84m. The upper structure is studied in an overall model. The following options were used for this project:

• Profile check and optimisation according to EC3

• Non-linear calculation of the structure

• Second-order calculation

• Stability check

The nodes in the steel structure - with profiles in different directions - are studied in a detailed 3D plate model. This gives an extra view and better insight into the forces in the different parts.

Emporia Towers, Bratislava, by Iguba

The project relates to the static of the reinforced concrete structure (C30/37) for the Emporia Towers Building in Bratislava – Slovakia, which will be constructed from January 2008 to May 2009. The supporting structure of the building is made of reinforced concrete from spilt concrete consisting of vertical wall and horizontal board elements forming a compact unit with transversal as well as longitudinal stiffening in the horizontal and vertical planes.

The foundation and the bearing structures were designed according to ENV 1993-1-1:1992 Eurocode 3.

For the static calculation, the 80 most dangerous combinations were calculated according to ENV 1993-1-1:1992 Eurocode 3 with coefficient 1.35 in two basic combinations (bearing capacity and deformations).
