plate at the widest point to a 70-foot-
(21.3-meter)-square floor plate at the
narrowest; this narrowest floor plate was later
revised to an 81-foot (24.7 meter)-square,
responding to economic demands for more
floor area and less variation in apartment size.
This change, however, had the impact of
increasing wind pressure on the building. In
response, a double-height “blow-through”
floor was introduced at level 83, which allows
wind to pass through the structure at a high
point (see Figure 5). Tuned sloshing dampers
at levels 83, 93, and 94 provide additional
wind-motion accommodation.

Anyone got the render skills to do a side-by-side?
