EXPO roof, Hanover

For the EXPO 2000 world exhibition in Hanover, the EXPO roof was an innovative large-scale timber structure in terms of dimensions, construction and design. The large roof with a total area of 16,000 m² is made up of ten individual umbrellas, each spanning a base area of 40 m x 40 m at a height of over 26 m. Each canopy is subdivided into several elements: a tower structure, a central steel connecting node, four cantilever beams and a double-curved lattice shell with four shell surfaces. The conical tower structure is formed by four solid silver fir trunks and triangular bracing plates made of glulam.
