Glickman, Fallingwater’s
Structural engineer forgot
the negative reinforcement
• He was referring to the
reinforcement for negative
bending moment, which
causes compression in the
lower part of each
cantilever beam and
tension in the upper part
• Any beam made of
reinforced concrete, the
concrete resists the
compression on the beam
and the steel bars resist the
tension
• after workers removed the
framework from the
concrete of the master
bedroom terrace, two
major cracks appeared in
the terraces parapet
