Nemetschek Engineering User Contest 2009 • Category 4: CAE Industrial Buildings & Plants 171 4 The columns of the steel structure are aligned in a way that the front flanges of the column sections have the same outline dimensions to allow easily assembly of the sound damping panels. Therefore additional eccentricities had to be considered. The steel structure is designed for an easy disassembly to allow fast access to the machinery for maintenance and repair purposes. The following components are a part of the delivery of Wendt SIT GmbH & Co. KG: Engineering • Acoustic design of the enclosure elements including splitter silencers of the ventilation system. • Complete design, layout -, outline-, detail- and erection drawings. • Static analysis of the steel structure and structural parts of the enclosure including the consideration of seismic and wind loads. • Design of the ventilation system, fans and filters. • Design of the electrical equipment and lighting. Hardware • Structural steel structure • Platforms, stairs and ladders • Wall and roof panels • Ventilation systems and filters • Fans • Lighting • Seaworthy Packing Technical Data of the enclosure • GT-Compartment Length 10,6 m Width 8,4 m Height 6,7 m • GENO-Compartment Length 12,2 m Width 8,4 m Height 6,7 m • AUX-Compartment Length 10,8 m Width 5,0 m Height 3,05 m • Lube-Oil-Compartment Length 9,15 m Width 4,3 m Height 4,8 m Weight of the steel structure: ~ 27 tons per unit Area of wall and roof elements: 1700 m² Program description The following software was used for the calculation: ESA-Prima Win 3.100 (now named Scia Engineer). Advantages of the software During the design phase it was necessary to check a lot of different versions to find an optimized solution. Thanks to ESA-Prima Win these different checks could be realised very easily. The load cases were easily generated with the graphic load generator. The stress calculations and design of frame corners were executed with ESA-Prima Win as well. Special requirements The calculation considered the local seismic and wind loads.
