Thanks. That's very interesting as the building does indeed present a wide face relative to its depth. So if you're slender or wide, you put in a blow-through or two.

Makes me wonder if this solution is more acceptable in modern buildings, both aesthetically and financially, as many older buildings have had to solve the loading problem by other means.
"According to CAB, by law the space cannot be illuminated. The result is likely to appear as a dark horizontal band across the Studio Gang/bKL-designed building’s uppermost extremity."
I wonder why that is. Anyone?

New height on SSP is 1,191' or (364 meters?)

Hardly noticeable but better than nothing

Subtract 7'9" and you will get the new official height, according those drawings.

From SSP. those leaning columns are quite impressive, they look like they belong to an infrastructure work, like a bridge or something.

Although I am not sure why they are leaning.

First for Chicago's skyline: Open floor to cope with wind, keep residents from getting queasy



Blair Kamin

Cityscapes

July 23, 2017

Quote:
The engineers for Chicago's future third-tallest skyscraper had issued a warning: Wind tunnel tests showed that the plan for the building, three thin, interconnected high-rises designed by star architect Jeanne Gang, had a flaw: High winds would push it around, making people inside feel like they were on a storm-tossed ship.

According to the engineers, the design for the Vista tower "would result in building occupants feeling ill and possibly afraid for their safety," Chicago's zoning administrator, Patricia Scudiero, wrote in an April 26 letter to Jack George, a lawyer for project's developers.

To prevent that, the developers requested — and the city OKed — an unusual change to the already-approved plan for the building: The 83rd floor of the 98-story, 1,198-foot East Wacker Drive tower will be an empty space that Chicago's famous winds can blow through. If all goes as planned, this so-called "blow-through floor" will ensure that the riverfront tower's residents and guests of its hotel won't be grabbing for motion-sickness medicine.

Such measures have started to pop up among the supertall, superslender skyscrapers that are altering skylines in Chicago, New York, Dubai and other glittering city centers where the super-rich and the merely rich choose to live. Although experts say the Vista tower's blow-through floor will be the first of its kind in Chicago, structural engineers here already have adopted other measures, both inside and outside buildings, to steady ultrathin skyscrapers against the wind.
