Today we were given a tour of various buildings around the UIUC campus that were examples of large arched ceilings. The ceilings all had very exact placement of support systems such as buttresses and flying buttresses in order to distribute the weight carefullyto the side of the structure and eventually to the ground.
The beams across the ceilings had
to be able to withstand pressure from
any direction in order to ensure that high
winds and other natural forces could not
affect the integrity of the building.
This weight of this portion of
the building (above photo) is supported
from the top as well as the bottom,
making it appear as if it is hanging.
(see photo left)
The support for the weight of
the large ceiling in this building
(right photo) comes not from the
actual walls, but from the metal
structure within them. This building
was created for the purpose of indoor
practice and thus has a very large space
to cover with its ceiling, creating the
need for main beams that run the
building lengthwise, using more material.
