Primary steel structure - Metro station Strizkov-Prague Used software • NEXIS 32 (ESA-Prima Win) Metro station Strizkov-Prague The project regards the design of the primary steel structure of the metro station of Prague-Støížkov. The new metro station Støížkov in Prague is designed and built as a special structure with a high esthetical level. The hall structure is about 160 m long, 42 m wide and 20 m high. Two crossed main hingeless arches with a span of 160 m are fixed to concrete pylons. The roof structure is suspended on the main arches by a system of prestressed rods and supported by columns around the roof. The major part of the members is a circumflex with a variable cross-section (the majority of the profiles are box welded from a plate thickness of 10-35 mm, except the columns, which are welded I profiles). The geometry of all parts is very difficult for the design, the manufacturing and the erection. The whole structure was built under direct supervision of the architect. The weight of the structure is about 950 tonnes. Quote of the jury: “The design and erection of this prestigious and eye-catching structure would not have been feasible without extensive and clever use of software”
