RELATIONSHIPS BETWEEN ARCHITECTURAL AND STRUCTURAL FORM 45▲ 3.48 The Mediatéque ‘hovers’ and expresses instability inthe atrium.▲ 3.49 Schools of Geography and Engineering, Marne-la-Vallée,Paris, France, Chaix & Morel, 1996. Vault-like roofs between blocks.envelope into the building, behind the structure. Unexpected and spectacular,structure enriches both the interior space and the buildingexterior.Upon entering the atrium, one discovers a third ‘tube’, the Mediatéque.Compared to the supporting structures of the Delibératif and thePresidential offices, which due to either splaying or tapering legs appearvery stable, the clusters of props under the Mediatéque suggest instabilitydue to the way they converge towards a point at floor level (Fig.3.48). It seems that unequal floor loading could cause the tube to topple.Only the relatively large diameters of the props themselves andtheir considerable bending strength avert such a catastrophe. So, withinthe space of a few metres where the giant X-columns ground and stronglybrace the building, a quite different structural form is encountered thatspeaks of fragility and creates an impression of the Mediatéque ‘hovering’or at least resting very lightly on its supports.The new Schools of Geography and Engineering complex, Paris, alsoincorporates contrasting architectural and structural forms (Fig. 3.49).Three parallel rectilinear blocks are separated by courtyards partiallyenclosed by curved vault-like forms. While the main blocks are structuredwith conventional reinforced concrete walls and frames, thecurved infill forms do not rely, as one might expect, on arches, but on anelaborate tension system. Their roof curvature follows concave catenarycables tied down at each end to foundations and pulled upwards at eightpoints along their lengths by tension rods hanging from the main blocks(Fig. 3.50). The fineness of the cables and rods contribute to achievingthat often sought-after impression of ‘floating’ (Fig. 3.51).This unusual structural system plays a significant pedagogical role in theschool life, illustrating principles of structural mechanics to generations
