Membraneroofing and free-form member SystemThe Landmark of the Expo
Shanghai 2010 is the central Boulevard. Via the round 1 km long and 100 m
wide axis, which stretches across the entire site to the Huangpu river,
the visitors are guided to the various national and theme-based
pavilions. It forms the central entrance area and provides 350,000 m2
effective area for numerous facilities for the exposition. The Expo
Boulevard is covered by a membrane roofing with a total surface of
65,000 m2 with a free span of almost 100 m. The roof is carried by 19
interior and 31 exterior masts and by six funnel shaped framework shells
consisting of steel and glass. It has a height of 35 m and a free
projection of 70 m. These so called sun valleys direct natural light
into the basements. The Expo Boulevard is one of five buildings, which
will remain after the world exposition to form the centre of a new urban
district of Shanghai in the long run.Membrane roof and sun valleys: Knippers Helbig Advanced Engineering, Stuttgart, GermanyEnergy scheme: Scholze Consulting, Leinfelden-Echterdingen, GermanyGross floor space: 280,000 m2Surface of membrane roof: 65,000 m2Span: 100 mSurface of free-form member system: 31,500 m2Dimension boulevard: 100 m x 1,000 mRealisation period: 2006 – 2010
