Pendentive at the Chicago Cultural Center
PENDENTIVE: A curved triangle forming the transition from the circular plan of a dome to the polygonal plan of its supporting structure.
Here is a pendentive at the Chicago Cultural Center, which was originally the Chicago Public Library. Click on the image to enlarge it. Notice the letters “CPL” (Chicago Public Library) around a “Y” shape symbolic of the branches of the Chicago River.
