The structural design of this pavilion includes two rectangular pavilion blocks displaced parallel to each other, comprising 690 m2 of exhibition space in all. Main stairs are located between the two blocks. In addition, there is a spiral staircase between ground floor and upper floor.
The characteristic feature of the structure is the arrangement of the upper storeys, which are suspended from three rows of tubular steel columns, so that they span over the ground floor and cantilever a distance of 7.0 m and 14.0 m, respectively, at the ends. The upper storey of each block comprises two Vierendeel girders integral with the longitudinal facades and interconnected by cross beams at roof and floor level. The girders are pin-jointed to brackets on the columns, which are spaced at 14 m centres in both directions. There is horizontal lattice bracing in longitudinal direction at roof level and transverse bracing in the end faces of the upper storeys. Steel trough decking serves to stiffen the upper floors. Wind forces are transmitted by the eight external columns fixed in foundation pockets in the reinforced concrete basement structure. The 1800 mm dia tubular columns are of welded construction, from 15 mm thick plate, stiffened with internal diaphragms. The Vierendeel girders, which are 4.24 m deep, comprise welded I-section chords, 620 mm deep, and HE 600 M uprights spaced at 3.50 m centres. Due to transport restrictions the Vierendeel girders had to be brought to the site in pieces, field joints being made at the mid-point of the depth of the uprights. Transverse beams are spaced at 1.75 centres and have bolted connections.
The ground floor is glazed. The Vierendeel girders in upper storeys have stainless steel cladding with opening windows provided with double glazing.
