A Vierendeel truss, named after its Belgian inventor, is one without diagonals. In a contemporary updating of Victorian engineering, a key feature of the steelwork is a Vierendeel truss encircling the first floor of the building which has created a huge, uninterrupted space at ground level facing into Pancras Square. The parallel chord truss, or flat truss, gets its name from its parallel top and bottom chords. Why the Vierendeel? THE VIERENDEEL FRAME, or truss as it is more popu- larly but inappropriately called, is a series of rectangular frames which achieves stability by the rigid connection of the vertical web members to the top and bottom chord. Each cantilevered girder is propped towards its outer end on an inclined steel post that tapers at both ends, and these are linked by horizontal tubular members and diagonal bracing to form what is in effect a gigantic Vierendeel truss that runs along the whole south side of the building and also carries the glass. The Vierendeel - School of Architecture - The. If you look at the glazing you can make out the angled struts bracing the Vierendeel.
