I am not familiar with the Clinton
Library, I will have to look at that one. The biggest advantage they have
working for them is the lack of seismic requirements. Having to allow for a
good seismic vertical bounce would add another level of fun to the concept.

seem that different from the William Jefferson Clinton Presidential Library in Little Rock.
Except that cantilever is longer.

Actually, I saw a work up on this building and the engineering is
pretty impressive. They didn’t just cantilever beams out, each box is
full story height trusses in the side walls with an interesting anchorage
geometry engaging a thorough “whole building” structural system.
It may look funny, but
from what I read the performance is very good and the engineering creative to
say the least.

a great looking picture.
I wonder what will be the experience those at the extreme ends of the
cantilever when there are mild seismic tremors or under the action of strong
if a few of us go to the roof and practice jogging, will the glass in the
window frames rattle?
in this building must have been given lessons in bravery and taught
to dismiss deflections and vibrations with contempt and even been persuaded to
actually enjoy them.
picture is going to create a lot of problems for engineers who battle
technologists (while designing Industrial buildings) and architects.
structural engineers, are notorious for making unreasonable demands for
space for supports like ugly columns, braces, etc when they are not really
necessary as this picturre clearly proves.
amount of cantilevering is okay!!
can't design it with such an alarming cantilever?
make way for those who can!!
