The roof of Thomas Deacon
Academy consists in a single-layer space frame. This structure is
composed of main arches, in bent profiles IPE 300 and a tubular
structure, which, on one hand, gives overall stability of the
structure, and, on the other hand, prevents the arches from buckling.
Originally designed with bolted joints composed of plates, the node
consists in two half spherical shells, bolted through the web of the
IPE; both parts of the node are bolted with high-strength bolts.
The bracings, composed of circular pipes, have rigid connections to the
nodes, allowing transmission of bending moments and shear forces. |
