Jurn De Vleeschauwer Email: [email protected] Website: www.stendess.com A steel and concrete engineering company Stendess can vouch for the total stability analysis of projects. Our approach covers the initial study trough to the end project. With its in-house know-how in steel as well as concrete, the firm is able to offer full study pack-ages for both materials. Thanks to its accumulated know-how and its advanced infrastructure, Stendess can follow up on cross-border projects in accordance with most standards and codes: Eurocode, NBN, NEN, DIN, NF, AISC, British Stan-dards and specific national codes. Key activities • Industrial buildings: steel factories, power plants, depots, etc • Other buildings: service buildings, concert halls, sport facilities, swimming pools, apartment buildings • Bridge construction: all types of bridges • Off-shore projects: lock gates, Roro, oil rigs, … • Industrial equipment: silos, cranes, crane ways • Erection engineering: longitudinal and transverse repositioning, skidding, hoisting,… Type: Gas fired combined cycle power plant (800 MW) Location: Castelnou, Spain Owner: Castelnou energia S.L. Engineering office: Ingenieursbureau STENDESS N.V., Lovendegem, Belgium Contractor: CMI-group, Seraing, Belgium Total steel weight: ± 600 tonnes Dimensions: 18,5 m x 36,5 m x 65 m Building period: middle 2004 - middle 2005 Short description of the project It concerns the realization of 4 identical gas fired combined cycle power plants in Castelnou, Spain. The steel structure had to be designed to support a total equipment weight of ± 2000 tonnes and a total piping weight of 1250 tonnes. About 80% of this weight is situated at a height of ± 30 m. The whole project was situated in a seismic dangerous zone and a high wind speed zone. Use of ESA-Prima Win Description of technical questions solved by ESA-Prima Win The challenge in this project was to design a low budget supporting steel structure for a gas fired combined cycle power plant which was situated in a seismic dangerous and high wind speed zone and of which the to be supported weight (± 2250 tonnes) was situated at a high level above the ground (± 30 m), which is very defavorable in a seismic zone. The simulation of the seismic actions was done by static equivalent horizontal loads in accordance to the natural frequency of the structure. Finding the balance between a relatively low stiffness of the whole structure (in order to decrease the seismic impact) and a sufficient supporting structure with expectable deformations was a high creative demand in the static layout and the dimensioning of the structure. Description of our experience with ESAPrima Win when realizing the project For this project ESA-Prima Win proved its power to calculate at high speed large structures with a great number of bars and a great number of combinations. More, ESA-Prima Win proved that even for large structures the dynamic calculations could be done in an acceptable way and time. Even optimisation of such large structure didn’t give much problems.
