DESIGN AND CONSTRUCTION OF 'UNIVERSEUM' - THE SWEDISH NATIONAL SCIENCE CENTRE

摘要

Universeum was built in five sections: the exhibition area, the glass stair, the rain forest, the aquarium and the Swedish landscape area. This paper deals with the sections made of glulam structures, namely the exhibition area and the saw- tooth- shaped roof above the rain forest. Each part of the construction has a different function and design. The exhibition area was built as an open, flexible structure with three storeys, with overall dimensions of 50 x 18 rr? and a height of 17 in. This makes it one of the largest glulam buildings in Sweden to date. The roof strticture is a sawtooth-shaped glulam space truss, with a span of up to 35 in and a cantilever of 15 in over the street facade. The total length of the roof varies from 23 in to 58 in with the V-shaped cross-section. The somewhat complex roof has been analysed using a three-dimensional finite-element method in order to evaluate the deflections and behaviour of the space truss. The dowel joints were designed according to the data from the FEM model.
