THE VIERENDEEL FRAME, or truss is a

series of rectangular frames which

achieves stability by the rigid

connection of the vertical web

members to the top and bottom chord.

The Vierendeel's origin dates to 1896.

The Belgian engineer Arthur

Vierendeel was the founder of

vierendeel truss.

The two reinforced concrete cores, located on the

east and west sides of the building, are the only

vertical load-carrying elements of the tower that

extend down to the mat foundation; achieving one of

the owner's objectives—a column-free lobby.

The eight gravity-load columns on the typical office floor plate are transferred to the

cores by three sets of two-story-deep trusses. which are the only vertical load-carrying elements that extend to the foundation.

Two primary trusses that span east-west—104’ between the cores and two secondary trusses that cantilever 33’ north and south

from the primary trusses.Each core measures 72’ in the

north-south direction and 38’-10” in the east-west direction; with

wall thickness of 4’-0” at the base to 1’-3” at the top.

The trusses also link the cores together, and in

essence, behave as a large moment-frame to resist east-west lateral

forces.
