Ingenieursbureau Zonneveld b.v. Is involved in many different activities. It has a vast experience with nonresidential building and housing, and is no stranger to infrastructure building and renovation building. The (approx. 40) employees are highly qualified in technical skills and can rely on a vast amount of experience. TABstarted as an advice office for undertakers and steel constructers and these roots can still be found in the fact that we design structures, which are economical while keeping in mind the practicability. TAB can offer you an impressing range of analyzing power and experience. We are confident that we can offer the most optimal solution to any problem. The last few years TAB has specialized in FEA and particularly in the design of structures in earthquake regions and design and follow up of the rough structure from start to end. The (approx. 8) employees are highly qualified in technical skills and can rely on a vast amount of experience. Your Project. Technical data of the project Project title Olympic Main Press Centre (MPC). Physical Location Athens - Greece. Site owner ATHENS 2004. Architect K. Kyriakides and associates S.A. Engineering office Karanikolas-Zoyopoulos-Papadopoulos Ltd, commissioned by Joint Venture Michaniki s.a. General contractor Technical Union s.a. The building is a 44.000 m² expansion of the existing congress center "Helexpo". The whole complex is approx. 65.000 m². The building contains conference halls with a capacity of up to 800 persons. The conference part has 5 building layers aboveground with a free span of 27,0 m. In all, a steel structure of approx. 4.000 tons of steel will be applied. After a thorough research as to the earthquake loads, so called "eccentric bracings" will be applied in the design. These elements for the stability combine a large stiffness with a favorable plastic behavior. Because of the importance of the building complex, the Greek government has determined the earthquake load to be 0,24 g (in stead of 0,16 g). There is also a stiffness demand. The frequency must be higher than 1,25 Hz. An intensive design process made it possible to meet both demands. Why is this project important? The Main Press Center (MPC) is the headquarters for the 5,500 written and photographic Press covering the 2004 Olympic Games in Athens. It will be located within walking distance from both the International Broadcast Center and the Athens Olympic Sports Complex, which will host nine out of the 28 Olympic sports being contested at the Games. Housed in a complex of three multi-level buildings taking up an area of more than 52,000 square meters, the MPC will comprise: A lobby area: help desk, banking services, travel agency, post office, message office, news desk, courier service, general store, technology store, pharmacy, and hairdresser. Press conference rooms The MPC will commence operation four weeks prior to the Opening Ceremony and will continue for up to four days after the Closing Ceremony (13 July - 3 September 2004). Two weeks before the Opening Ceremony, it will become operational on a 24-hour basis. In the MPC, the written and photographic Press will enjoy making use of a wide range of facilities and services, including: KODAK film-processing laboratory. Photo Work Area: workstations, photo helpdesk, photo-transport office and lockers for photographers. Press Work Room: workstations with pay telephones, competition-results pigeonholes, results printing, help desk, INFO 2004 terminals. Rental Agency space Catering: dining hall (international food court setting) and VIP dining area. Service Center: central help desk for Rate Card assistance. INFO 2004 - the Games INFO system. Ticketing services for the accredited press. Use of ESA-Prima Win ESA-Prima Win has been chosen for different reasons: The geometry of the buildings is quite complicated therefore a user-friendly interface was a must. Existing 3D CAD files could be used to quickly generate parts of the structure. Quite early in the design it became apparent that the asked for stiffness would be the predominant design factor. On the other hand we wanted an economical structure and at the same time one that demonstrated a favorable plastic behavior. Therefore it was very important to be able to quickly introduce modifications in the design and calculate the implications. ESA-Prima Win turned out to be an instrument very well suited to achieve the above-mentioned goals. We think that without the use of ESA-Prima Win it would not have been possible to do the design within the very short delay we disposed of. 73 SCIA User Contest Catalog
